User:Morphriz/Sandbox/Adolescent sexuality in the United States



Adolescent sexuality in the United States relates to the sexuality of American adolescents and its place in American society, both in terms of their feelings, behaviors and development and in terms of the response of the government, educators and interested groups.

According to the US Centers for Disease Control and Prevention, in the year 2007, 35% of US high school students were currently sexually active and 47.8% of US high school students reported having had sexual intercourse. This percentage has decreased slightly since 1991. Every year, an estimated 1 in 4 sexually active teens contracts an STD, and teenage pregnancy is 2 to 10 times more prevalent in the United States than in other similarly developed countries.

In the United States there is an ongoing debate regarding these problems and how to solve them. Some argue that more classical sex education are needed and some argue that only abstinence-only sex education should be taught. There have been efforts among social conservatives in the US government to limit sex education in public schools to abstinence-only sex education curricula.

Sexual behavior
Today both boys and girls are now "entering puberty at least two years earlier than previous generations. This means they are ready for sex earlier physically, but not emotionally or cognitively."

The percentage of teenagers who report they are currently sexually active has been dropping since 1991. By 2005, the overall percentage of teenagers reporting that they were currently sexually active was down to 33.9%. A lower number of sexually active teens is "quite positive in terms of their health and their well-being."

Despite the decreasing number, there are still some who are promiscuous. Approximately 15% of students will have sex with four or more partners by the time they graduate from high school. Many others, particularly boys, will lie about how much sex they are having. In one national study, 60% of boys said they had lied about something sexual and 30% had lied about how far they had gone.

Factors that correlate with teen sexual activity include:


 * "Individual—having a history of sexual abuse, depression, heavy alcohol or drug use.
 * Family—living in a single parent or stepparent household, living in a poor household, having parents with permissive values about sexual activity, having little supervision from parents, having siblings who are sexually active, feeling unloved, unwanted, or not respected by parents.
 * Community—having friends who are sexually active, having few positive experiences at school, living in a neighborhood with poor neighborhood monitoring."

Virginity loss
The average age of first sexual intercourse in the United States is 17.0 for males and 17.3 for females. Most American teenagers are virgins, and the percentage of teens who are virgins has been increasing. 43% of unmarried teenage girls and 42% of unmarried teenage boys have ever had sexual intercourse. In 2002, 46% of girls and 46% percent of boys had had sex by 19. Among younger teens, the majority claim to be virgins, and this percentage has risen over time.

16% percent of adults first had sex before age 15, while 15 percent abstained from sex until at least age 21. Girls will most likely lose their virginity to a boy who is 1 to 3 years older than they are. According to one study, almost 14 percent of teens lose their virginity in June, the most common month.

The teen's home, their partner's home or a friend's house is the most common place for virginity to be lost, with 68% of teens losing their virginity in one of those three places. The same study found that "the likelihood of a first sexual experience happening will increase with the number of hours a day teens spend unsupervised."

Surveys indicate that the majority of American teens who have had sex wish they had waited. Among sexually active girls, two-thirds say they didn't want to lose their virginity when they did or that they had mixed feelings about it. 1% chose to have sex when they were 13 or younger, 5% at 14 or 15 years old, and 10% at 16 or 17 years old.

Another 42% reported that losing their virginity before age 18 was not completely wanted, while the remaining portion of the sample waited until age 18 or older to have sex (wanted, 22%; unwanted, 21%). A first sexual experience that was unwanted or not completely wanted was strongly associated with future divorce. "If the sex was not completely wanted or occurred in a traumatic context, it's easy to imagine how that could have a negative impact on how women might feel about relationships, or on relationship skills. The experience could point people on a path toward less stable relationships."

Oral sex
Half of all 15- to 19-year-olds have had oral sex. That percentage rises to 70% by the time they turn 19, and equal numbers of boys and girls participate. The data indicates that many teens, particularly those from middle- and upper-income white families, don't consider oral sex to be as significant or meaningful as older generations do.

"There is discrepancy when it comes to willingness to perform oral sex [with] 22% of sexually active girls say[ing] their partner never performs oral sex on them, while 5% of boys say their partner never does." When girls provide oral sex "they do so without pleasure, usually to please their boyfriend or to avoid the possibility of pregnancy." This paradigm has entitled boys and disempowered girls, putting girls at a disadvantage. Adolescents who engage in oral sex but not intercourse report fewer problems with sexually transmitted diseases, guilt, and their parents, but also less resulting pleasure, self-confidence or intimacy with their partners.

Researchers believe that some teens, and particularly girls, engage in oral sex as a way to avoid vaginal intercourse. However, experts caution that "we need to move away from the idea that girls who engage in oral sex but not intercourse are 'technical' virgins – that you're not having sex because no one's penetrating you. Let girls know that every time you do something like that, you compromise yourself and give up some of your power."

Researchers believe that oral sex may have become more popular than intercourse for adolescents because teens believe it carries fewer physical and emotional risks. Experts have found that oral sex, as well as vaginal sex, was associated with negative consequences.

Contraceptive use
Among sexually active 15- to 19-year-olds, 83% of females and 91% of males reported using at least one method of birth control during last intercourse. Sexually active adolescent girls who wish to avoid pregnancy are less likely than those of other ages to use contraceptives (18% of 15- to 19-year-olds used no contraceptives, versus 10.7% average for women ages 15 to 44). Most non-virgins (78% of girls and 85% of boys) used contraception the first time they had sex.

Among adolescents, the most common methods of contraception are birth control pills (used by 43.5% of 15- to 19-year-old girls) and condoms (used by 22%). In 2007, 61.5% of high school students reported using a condom the last time they had sexual intercourse, up from 46% in 1991. While 90% of teens surveyed in one poll knew they could get an STD from having sexual intercourse, only 67% said that they use protection every time they have sex.

Abstinence
For the last 20 years abstinence rates among American adolescents have risen. The percentage of high school students in the U.S. who reported that they have ever had sexual intercourse dropped from 54.1% in 1991 to 47.8% in 2007 and to 43% in 2011. A cross-sectional survey 73,464 of adolescents in Minnesota conducted in 1998 found that fear of pregnancy was the most commonly cited reason for choosing abstinence, especially among girls, as well as boys who had caused a pregnancy in the past. Other reasons included a fear of sexually transmitted infections, a lack of desire, being afraid of getting caught, and the belief that sex was not appropriate for someone of their age.

Adolescents who have received sex education in school or church settings are less likely to be sexually active. For girls, they were 59% less likely and boys were 71% less likely. Epidemiologists at the Center for Disease Control emphasize that for sex education to be effective, it should take place before teens become sexually active.

Motivation for sexual activity
In a 2003 study, 89% of girls reported feeling pressured by boys to have sex, while 49% of boys reported feeling pressured by girls to have sex. In contrast, 67% of boys felt pressured by other boys, while 53% of girls felt pressured by other girls.

A 2005 poll found that, of the teens surveyed, the reasons they had sexual intercourse for the first time were: The vast majority of 13- to 16-year-olds, 87%, have not had sexual intercourse, and 73% have not been sexually intimate at all. Sexual activity is much more common among 15 to 16 year-olds (41%) than 13 to 14 year-olds (14%).

Three quarters of them have not because they feel they are too young, and just as many say they have made a conscious decision not to. Girls are more likely than boys to say they have made a conscious decision to wait (81% vs. 67%) and are more likely to believe they are too young (82% vs. 67%).

Girls who date or hang out with older boys are "more likely to be pressured into having sex, more likely to get a sexually transmitted disease, and more likely to experience an unwanted pregnancy." They also have a higher correlation with substance abuse and a combination of sex and drug use.

Alcohol use
A survey by the National Campaign to Prevent Teen Pregnancy found that "7% of youth used alcohol the first time they had sex, and 6% used alcohol the most recent time they had sex."

Boys will use drugs and alcohol for different reasons than girls. Boys are more likely to use in order to relax and to prevent premature ejaculation. Girls will often become intoxicated before engaging in sexual activities because it "numbs the experience for them, making it less embarrassing and less emotionally painful."

For girls to "tolerate" having casual sex they "have to get loaded. This whole hooking up culture is making them unhappy and anxious.  It requires them to find ways to manage these very intense situations, namely drugs and alcohol."

Hooking up
Increasingly, teenage sexual encounters in the United States do not occur in the context of a romantic relationship, but in an impersonal, merely sexual "hook up." More than "half of sexually active teens have had sexual partners they are not dating." This is a "a genuine and puzzling change in teen sexual behavior" and a "profound shift in the culture of high school dating and sex." A Friends With Benefits relationship is "always a disaster for somebody. We're human beings, we develop feelings, and somebody always gets hurt as a result."

"Casual teen attitudes toward sex — particularly oral sex — reflect their confusion about what is normal behavior... [T]eens are facing an intimacy crisis that could haunt them in future relationships. 'When teenagers fool around before they're ready or have a very casual attitude toward sex, they proceed toward adulthood with a lack of understanding about intimacy.'"

Though a girl is "far more likely to feel used and abused after a typical" hook up, the "impersonality of twenty-first-century adolescent sex victimizes girls" and "plenty of harm" is done to boys as well. When taking part in hookups "the kids don't even look at each other. It's mechanical, dehumanizing.  The fallout is that later in life they have trouble forming relationships.  They're jaded." James Wagoner, president of Advocates for Youth, worries that "if we are indeed headed as a culture to have a total disconnect between intimate sexual behavior and emotional connection, we're not forming the basis for healthy adult relationships."

The "explosion of sex without meaning" among American teens "is deeply symptomatic. Emotional deadness, disengagement, and constriction are increasingly the norm. (Oral sex is, after all, 'just something to do.') 'Sexual addiction,' [the medical] term for moving from sexual experience to sexual experience without ever being satisfied, is prevalent. Meanwhile, for many kids precocious sexuality represents not freedom and experimentation but is a byproduct frequently seen with sexual trauma: compulsively driven activity that both expresses and aims to manage the effects of chronic intrusion and overstimulation."

Oral sex
Almost half of boys (47%) believe that oral sex is "not a big deal." Slightly more than a third of girls (38%) feel the same way. Despite this, there is a large "discrepancy when it comes to willingness to perform oral sex" with girls giving, and boys receiving. Of sexually active girls, 22% say their partner never performs oral sex on them, while 5% of boys say their partner never does." Oral sex is "now commonly performed by very young girls outside of romantic relationships, casually and without any expectation of reciprocation."

Social and cultural aspects
"We've gone though a 30 year period when sexuality was the solution; it has now become the problem. It's like a drug in our culture.  Kids look upon it [sex] as a way of managing how they are feeling as opposed to of a way of expressing intimacy.  We have such disturbed family systems that kids have impairments of their ability to regulate their affective lives;... naturally enough they look at these things as their solutions."

Adolescents who are better students initiate sexual activity later than those who are poor students. Despite their behaviors, 90% of adolescents "agree that most young people have sex before they are really ready".

With regards to oral sex, experts have noted that casual attitudes towards it have made it so common that "we're talking about a major social norm. It's part of kids' lives." Along those lines, adolescents with personal and perceived peer norms that encourage adolescents to refrain from sex are less likely to engage in it. Girls as young as junior high age "with pitiable self-esteem... give oral sex sex to boys while insisting that they are not sexually active - an astonishing redefinition of sexual activity shared by most of their generation."

Definitions of virginity
Among young people engaging in some form of sexual activity, definitions of virginity differ. Of adolescents age 12–16, 83% believe a person is still a virgin after engaging in genital touching, and 70% said they believed one retained their virginity after having oral sex. However, 44% believed that one was abstinent after genital touching and 33% believed one could have oral sex and still remain abstinent. Of anal and vaginal sex, 14% believed you could engage in the former and 12% said you could participate in the latter while still remaining abstinent.

According to a 2007 study, "a large proportion of young people believe even an intimate level of sexual contact is abstaining from sex and being a virgin." If an adolescent engaged in a particular behavior they were more likely to believe that they still meet the definition of a virgin. Virginity is usually defined as the state of a person who has never engaged in sexual intercourse.

Pornography
Between the 3rd and 10th grades more than 90% of children will be exposed to pornography. Young people who view online pornography are 3.5 times as likely also to report clinical features of major depression, and the pornography may be contributing to their depression. They are also much more likely to report substance abuse and other deviant behaviors. As "pornography is "a cultural force that is shaping the sexual attitudes of an entire generation" and a "major form of sex ed today for boys, it's going to have dire consequences for the boys, for the girls, and for the culture."

Physical effects
As their brains are still not fully developed, adolescents and young adults have difficulty predicting the consequences their actions will bring and thus often underestimate their risk for adverse consequences. Research into adolescents' sexual behavior in situations outside traditional dating situations, commonly referred to as hooking up, shows that adolescents underestimate the risk involved in such situations. With all the issues and problems relating to adolescent sex, "ideally, they [adolescents] won’t be having sex.".

Pregnancy
Teen pregnancies—defined as pregnancies in women under the age of 20, regardless of marital status—in the United States decreased 28% between 1990 and 2000, from 117 pregnancies per every 1,000 teens to 84 per 1,000. Teenage birth rates peaked in 1991, when there were 61.8 births per 1,000 teens, and the rate dropped in 17 of the 19 years that followed. From 2009 to 2010, the teen pregnancy rate dropped 9%, the biggest one year drop since the 1940s.

Slightly more than half of Hispanic and black women will become pregnant before the age of 20. Asian-Americans have the lowest rate of pregnancy before the age of 20 of any ethnic group. Statistics also vary regionally. A swath of southern states from New Mexico to Mississippi saw rates of more than 50 births per 1,000 teenage girls. In New England, by contrast, most states had less than 20 births per 1,000 girls.

One in four American women who had sex during their teenage years will have a baby before they are married, compared to only one in ten who wait until they are older. Even more will experience a pregnancy. Of women who have sex in their teens, nearly 30% will conceive a child before they are married. Conversely, only 15% of women who don't have sex in their teens will become pregnant before they are married. Of all women, 16% will be teen mothers.

International comparisons typically place US teen pregnancy and teen birth rates among the highest in the developed world. For example, a 2001 study by UNICEF found that the US teenage birth rate was the highest among 28 OECD nations in the review; in a 1999 comparison by the Guttmacher Institute, U.S. teen pregnancy and teen birth rates were the second-highest among the 46 developed countries studied. In 2002, the U.S. was rated 84th out of 170 World Health Organization member countries based on teenage fertility rate.

According to an international comparison by the Guttmacher Institute, teen pregnancy and childbearing levels are higher in the US largely because of differences in contraceptive use. Sexually active teens in the US are less likely to use any contraceptive method and especially less likely to use highly effective hormonal methods, primarily the pill, than their peers in other countries. The research also found that US teens who become pregnant are less likely to choose abortion, whether due to lack of access, higher levels of antiabortion sentiment, or greater acceptance of teen motherhood.

Sexually transmitted infections
Each year, between 8 and 10 million American teens contract a sexually transmitted disease. According to the U.S. Centers for Disease Control, almost half of the 19 million sexually transmitted diseases reported in the U.S. occur in young people, ages 15 to 24. Lloyd Kolbe, director of the CDC's Adolescent and School Health program, called the STI problem "a serious epidemic." The younger an adolescent is when they first have any type of sexual relations, including oral sex, the more likely they are to get a STI.

A 2008 study by the CDC found that one in four teen girls, or an estimated 3 million girls, has an STI. The study of 838 girls who participated in a 2003–04 government health survey found the highest overall prevalence among black girls; nearly half in the study were infected. This is compared with 20% among both whites and Mexican-American teens. The same study found that, among those who were infected, 15% had more than one STI, and 20% of those who said they had only one sexual partner were infected.

In the CDC study, 4% were infected with chlamydia, historically the most prevalent of all STIs in the general population. More than a third of all chlamydia cases occur in those aged 15 to 19. Additionally, 2% were infected with herpes simplex. The herpes infection rate fell between 1988 and 2004 among teens as well as the overall population.

HPV
Human papillomavirus (HPV) is the most common STI among teens as well as adults. In the CDC study, 18% of teen girls were infected with HPV. Another study found that HPV infections account for about half of STIs detected among 15- to 24-year-olds each year. While HPV infections may not cause any disease, it can cause genital warts and cervical cancer.

An HPV vaccine protects women against some types of HPV, but not every type. Even after being vaccinated girls can still come down with HPV related cancers and genital warts. The vaccine is only effective before exposure to HPV. "One concern within the medical community is that the vaccination will provide a false sense of security."

Oral sex and STIs
Researchers from the Centers for Disease Control have noted that teenagers often don’t understand the risks associated with sexual activity. “Research suggests that adolescents perceive fewer health-related risks for oral sex compared with vaginal intercourse. However, young people, particularly those who have oral sex before their first vaginal intercourse, may still be placing themselves at risk of STIs or HIV before they are ever at risk of pregnancy,” the CDC wrote. "Several studies have documented that oral sex can transmit certain STIs, including chlamydia, genital herpes, gonorrhea and syphilis. Teenagers and young adults engaging in sexual activity are at increased risk of STIs or HIV.”

Cancer
HPV, the most common STI, causes many types of cancer including oral cancer and cancer of the cervix, anus, and penis. In recent years there has been a huge surge in HPV-associated oral cancers. Between 1988 and 2004, HPV-associated oropharyngeal cancers rose 225%. "Oral sex is the primary culprit." The incidence of HPV-associated cancers that affect men is growing along with the cancers that affect women.

Psychological effects
For teens, "having sex changes you. It is emotionally powerful and there are risks involved." Dr. Drew Pinsky has also said "All of us want young people to make better choices, to delay their sexual contact, to make sure that they fully understand the implications of those choices -- which of course, they never do..."

According to Harvard Medical School's Mark O'Connell, adolescents "often haven't achieved the emotional, even neurological, maturity necessary for making autonomous and self-aware sexual choices." Emotional, social and cognitive development continues well past adolescence. As the frontal lobe of the brain, which houses complex thinking, understanding cause and effect, controlling impulses, and judgment, is not fully developed until a person is in their 20s, "teens are less prepared to think about 'if I do this today, what will happen to me tomorrow?'"

With their still-developing brains, teens do not yet possess the ability to either fathom the physical and emotional consequences of sex or to deal with them once they happen. In one study, among those who had had both oral and vaginal sex, 60% reported at least one negative effect, such as feeling used, getting pregnant, contracting a sexually transmitted infection, or feeling bad about themselves.

Production of oxytocin increases during the adolescent years, and it is key to monogamy and long-term attachment. Oxytocin is "nature's way of weaving people together." Girls have more of it and may be more sensitive to it. Psychologists theorize that oxytocin will make them care about relationships and feel connections with others more intensely than boys. This is "a logical explanation for why girls are in turmoil after a hook up and boys are not".

Psychological problems and emotional distress
"We tend to focus on the health consequences of having sex, like pregnancy and STIs, but we also need to talk to [teens] about all the emotional consequences," experts say. Disease and illness related sexual activity is epidemic, but "the psychological outfall isn’t far behind." Those who have first sexual intercourse before 15 have higher rates of mental illness.

Sex for teens is not "without risk. It can take a toll on the soul, dehumanizing unsuspecting students who tumble too soon into the world of hooking up, not knowing enough about sex or themselves to avoid getting hurt." Despite "societal shifts in sexual standards, human development remains pretty much the same. Kids are still emotionally vulnerable and volatile – more so if they are sexually active".

Teens are not in the dark about sex itself, "they're in the dark about the implications of [sexual behavior]. They're in the dark about the emotional reality, they're in the dark about the biological reality, they're in denial about this thing that has become a drug in our culture, rather than an expression about intimate relations." He continued, "It's too far the other way: It's not that they don't know about it, they know everything, but at the same time, they know nothing. And that's the problem. So the human piece is left out, the human reality is taken away, it's all thought of very casually."

Researchers have found that cutting is linked to higher levels of risky sex among teenagers. "Habitual cutting is a way of managing intense emotional distress. It makes sense that the level of impulsivity and risk taking would also be higher in these teens." Cutting, even once, is "a warning sign that they are overwhelmed in some way."

Depression and suicide
Longitudinal research has shown "a significant association between teenage sexual abstinence and mental health." In a broad analysis of data from the National Longitudinal Study of Adolescent Health, researchers found that engaging in sex leaves adolescents, and especially girls, with higher levels of stress and depression. "Depression, anxiety and increased stress accompany the abuse of alcohol and drugs also observed in sexually promiscuous teens."

Research has found "a dramatic relationship" between sexual activity among adolescents and "multiple indicators of adolescent mental health. Compared to abstainers, membership in any of the risk clusters was associated with increased odds of depression, serious thoughts about suicide, and suicide attempts." Sexually active girls are more vulnerable to depression, suicidal ideation, and suicide attempt than sexually active boys, but there is little difference between boys and girls who are not sexually active. Risk for depression is "clearly elevated" for the sexually active of either gender.

“Teenage sexual activity routinely leads to emotional turmoil and psychological distress. [Sexual permissiveness leads] to empty relationships, to feelings of self-contempt and worthlessness. All, of course, precursors to depression.” Experts recommend that sexually active adolescents be screened for depression and be "provided with anticipatory guidance about the mental health risks of these behaviors." Experts recommend that parents and health professionals help teens prepare for and cope with the emotions attached to sex.

Casual sex
Casual attitudes amongst adolescents toward sex and oral sex, in particular, "reflect their confusion about what is normal behavior." When taking part in hookups, "the kids don't even look at each other. It's mechanical, dehumanizing." Especially among younger teenagers, casual sex is associated with depression. This impersonality is harmful to both girls and boys; however, girls are especially at risk of becoming victims in casual sexual relationships.

Studies show "what many teens come to find out on their own: Even if sexual activity seems casual, it often is not. A casual hookup on a Friday night might not feel that way a month down the road." When having casual sex teens are "pretending to say it's just sexual and nothing else. That's an arbitrary slicing up of the intimacy pie. It's not healthy." Depression, alcohol abuse, anorexia, and emotional disturbance can all afflict adolescents as a result.

When adolescents engage in casual sexual relationships, they proceed toward adulthood with a lack of understanding about intimacy. Experts worry that "if we are indeed headed as a culture to have a total disconnect between intimate sexual behavior and emotional connection, we're not forming the basis for healthy adult relationships." Physician Bernadine Healy states, "Both as doctor and mother, I can't help but believe that our anything-goes society, in which impulses are immediately satisfied and sex is divorced from love and bonding, is simply not healthy physically, emotionally, or spiritually."

Males and females experience sex differently. Males are more able to shrug off a one-night stand, but "girls are more confused afterward... and in general suffer a loss of self- esteem." When girls hook up they "don't count on... oxytocin, a chemical produced in the brain to promote feelings of connection and love. Oxytocin is most commonly associated with breast-feeding; it's what helps a mother bond with her infant."

Known as "cuddling hormone" or "hormone of love," oxytocin is also produced during sex, causing the partners to form emotional attachments with one another. "The more intense the sex, the more oxytocin." Males also get a bigger dose of testosterone, which suppresses the oxytocin." This is "a logical explanation for why girls are in turmoil after a hook up and boys are not".

Teenage relationships
Even when teens are in a romantic relationship, sexual activities can become the focus of the relationship. Not only are such relationships less sustained, they are often not monogamous and they have lower levels of satisfaction than relationships that do not have sexual activities as their focus. The "early initiation into sexual behaviors is taking a toll on teens' mental health" with dependency on boyfriends and girlfriends, serious depression around breakups and cheating, and suffering from a lack of goals as possible results.

Adult relationships
When adolescents engage in casual sexual relationships they do not develop skills such as trust and communication that are key ingredients in healthy, long-lasting relationships. In purely sexual relationships, adolescents pick up "a lot of bad habits" and don't learn "to trust or share or know how to disagree and make up," according to Laura Sessions Stepp, author of Unhooked: How Young Women Pursue Sex, Delay Love, and Lose at Both. They become jaded and as a result later in life, they have trouble forming adult relationships. "They don't learn to build that emotional intimacy before they get physically intimate. In the long term, that develops bad relationship habits."

Experts worry that when teens have sex before they're ready then they undervalue the experience and that leads to a cynical view later on. "[T]hey can develop a kind of negative attitude about life in general, that things aren't that special and they aren't that wonderful and what's the big deal about a lifelong commitment and a family commitment? They're disappointed, probably because they weren't mature enough to understand the meaning of it, and it's kind of made them kind of cold to the idea of commitment in other ways."

Those who lose their virginity in their 20s or later are more likely to find happiness in romantic relationships later in life than those who lose it during their teenage years. “Individuals who first navigate intimate relationships in young adulthood, after they have accrued cognitive and emotional maturity, may learn more effective relationship skills than individuals who first learn scripts for intimate relationships while they are still teenagers.”

When a man achieves orgasm his oxytocin levels can rise up to 500% of their normal levels. "When "a man ejaculates, he bonds utterly with" his partner. By the time a young man has reached his early twenties, his girlfriend or his wife will become his primary emotional caregiver.  By having casual sex while he is younger, however, he will learn to suppress the natural bonding mechanism that comes with sex and oxytocin.  If this happens, he may not be able to establish an emotional relationship with a woman, who does view sex as connected to intimacy, and will be more likely to become depressed, commit suicide, or die from illness.

Oral sex
Teens believe that oral sex is less risky to their emotional and physical well being than vaginal sex, but experts at the University of California do not believe this conclusion is warranted. They found that oral sex, as well as vaginal sex, was associated with negative consequences.

With regards to oral sex, it is almost always the boys who receive it and the girls who give it. When girls provide oral sex "they do so without pleasure, usually to please their boyfriend or to avoid the possibility of pregnancy." This paradigm has entitled boys and disempowered girls, putting girls at a disadvantage. Adolescents who engage in oral sex but not intercourse report fewer problems with sexually transmitted diseases, guilt, and their parents, but also less resulting pleasure, self-confidence or intimacy with their partners.

Of adolescents engaging in oral sex only, girls were twice as likely as boys to report feeling bad about themselves and nearly three times as likely to feel used. Boys who engaged in oral sex were more than twice as likely as girls to report feeling more popular and confident.

Psychological effects specific to girls
Girls are "at particular risk for experiencing negative social and emotional consequences of having any type of sex," including oral sex. "Early sex is a threat, and it remains a greater threat to girls than to boys." "Just because a girl has matured physically, doesn’t mean she’s socially or psychologically mature." Additionally, early sex poses a greater physical threat for girls than for boys. Adolescent girls are especially vulnerable to sexually transmitted infections.

Some research suggests that females are not biologically or evolutionary equipped to handle casual sex. Girls are more than twice as likely as boys to say they felt bad about themselves and more than three times as likely to say they felt used as a result of engaging in sex or hookups. The hormone oxytocin, released during sex, affects women differently than men, so that "when women think they can have sex and walk away just like guys do, they're having to suppress thousands of years of evolution that tells them to cuddle, stay in bed, and look forward to tomorrow. When they get up and walk out, they feel depressed and don't know why."

"Young teen girls who engage in sexual activity to win the approval of a boy may find themselves disappointed when the relationship ends and may be at odds with their own value system." The American Psychological Association task force in 2007 found that an early emphasis on sexuality stunts girls' development in other areas. "When kids are about defining themselves, if you give them this idea that sexy is the be-all and end-all, they drop other things."

Casual sex
In a study of casual sex among adolescents, many girls believed they could have a purely sexual experience with no emotional ties, and they believed it was sexist to assume otherwise. However, the study found that both the girls and the boys who were hooking up often really were depressed and didn't feel very good about themselves. "All the experts who talk about teen sexuality maintain that... it's impossible" for girls to enjoy meaningless sex as much as boys. Girls will "inevitably regret what they did." Girls "particularly are suffering from the new regime [i.e. casual sex] and are having some lasting problems" as a result of it.

When asked if girls and women really wanted casual sex as much as men did, Dr. Drew Pinsky said he had spoken to them "by the thousands" and that they absolutely did not. The only reason they engaged in it, he said, was because they thought it was what they need to do in order to get the guy. The current paradigm of casual sex has left females "ambivalent, unhappy and uncomfortable."

Regret, depression, and mental illness
While teens may believe that their sexual activities are fine at the time, they may feel very differently in time and regret the choices they made. Research shows that 2/3 of sexually active girls wish they had waited longer before having sex. Of seniors in high school, 74% of girls regret sexual experiences they have had. Girls are more than twice as likely as boys to say they felt bad about themselves and more than three times as likely to say they felt used as a result of engaging in sex.

For girls, even modest involvement in sexual experimentation elevates depression risk. Sexually active teenage girls are more than twice as likely to suffer depression compared to those who are not sexually active. More than 25% of sexually active girls are depressed all of the time, most of the time, or a lot of the time, but more than 60% of girls who are not sexually active are never depressed.

Sex therapists have found that the roots of sexual issues facing adults often date back to regretful teenage experiences. Research has also found that being abstinent in the teen years was associated with better mental health at age 29. Girls who were virgins at age 18 were also less likely to have a mental illness at age 40.

Dating violence
Girls who have engaged in sexual intercourse are five times more likely than their virgin peers to be the victim of dating violence. Girls who were intentionally hurt by a date in the past 12 months are at a "significantly elevated risk for a broad range of sexual health concerns and for pregnancy." Girls who have been victims are also twice as likely to report high levels of multiple sexual partners.

School work
The context of sexual relationships may determine whether the sex is harmful or not to a young person's GPA, as well as to their chances of dropping out of school. University of Minnesota sociologist Eric Grodsky says that, for teens, "sex outside of a romantic relationship may exacerbate the stress youths experience, contributing to problems in school," which prompted sociologist Peggy Giordano of Bowling Green State University to offer "some comfort to parents who may be concerned that their teenage son or daughter is dating" and that teen sex, on its own, is "not going to derail their educational trajectories."

On the other hand students who hook up and have casual sexual encounters are more likely to do poorly in school and get lower grades. They also care less about school and get in more trouble. Boys who hook up have GPAs that are .3 lower than virgins and girls who have casual sex have GPAs that are .16 lower. They also get suspended or expelled more and had lower expectations of going to college.

All kids who have sex, even if they are in a relationship, are more likely to skip school or just drop out altogether. Additionally, adolescents who start having sex before they reach age 16 are much less likely to go to college.

Marriage
Women who first have sex as teenagers are much more likely to divorce, especially if their first time was unwanted or if they had mixed feelings about it. Among sexually active girls, two-thirds say they feel this way. Girls who lost their virginity before the age of 16 are also more likely to divorce than those who lose it later.

Of women who had sex for the first time as teens, 30% divorced within five years, and 47% divorced within 10 years of getting married. The divorce rate for women who delayed sex until adulthood was far lower: 15% at five years, and 27% at 10 years. "There are down sides to adolescent sexuality, including the increased likelihood of divorce," according to Anthony Paik, associate professor of sociology at the University of Iowa. Researchers believe "that the early sexual experience leads to the development of behaviors or beliefs that promote divorce."

Age of consent
Each state has its own age of consent. Currently, state laws set the age of consent at 16, 17, or 18. The most common age is 16 (more than half of the states have this age limit); however, the five most populous states all have a higher age of consent (California: 18, Texas: 17, New York: 17, Florida: 18 and Illinois: 17).
 * age of consent 16: Alabama, Alaska, Arkansas, Connecticut, District of Columbia, Georgia, Hawaii, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nevada, New Hampshire, New Jersey, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Vermont, Washington, West Virginia
 * age of consent 17: Colorado, Illinois, Louisiana, Missouri, Nebraska, New Mexico, New York, Texas, Wyoming
 * age of consent 18: Arizona, California, Delaware, Florida, Idaho, North Dakota, Oregon, Tennessee, Utah, Virginia, Wisconsin.

Sexting
More than one fifth of teens have sent sexually suggestive text messages or nude photographs of themselves online. Teens who photograph or film themselves or receive photos of others, known as sexting, can be charged with child pornography. Others who post the photos online could also be charged with child pornography and face prison time.

Sexting is linked to psychological distress among teens. Those involved in sexting are more likely to report a suicide attempt, and have twice the odds of reporting depressive symptoms as students who aren't involved in sexting. "For girls who send the sexts... there is a disillusionment and a sense of betrayal when it's posted everywhere. When it gets forwarded to multiple boys at multiple schools and also other girls ... a girl starts getting called names and her reputation is ruined," according to Dr. Jill Murray.

Boys who are victims of sexually predatory teenage girls can also be devastated. Sexually predatory girls will ask a boy, particularly a sexually naive boy, for photos, and "he's sort of flattered and he feels like a big guy and then she sends them around." It can cause lasting harm.

Often girls who take racy photos of themselves "want to be admired, want someone to want them," according to Parry Aftab, an Internet privacy and security lawyer and volunteer for WiredSafety. "A lot of them are lonely and starved for attention. A lot of girls think they have no choice but to pose in this way. And then there are the thrill seekers who do it because it's edgy and cool."

Experts say that sexting poses a serious problem, partly because teens do not understand that the images are permanent and can be spread quickly. “It does not click that what they’re doing is destructive, let alone illegal.” “Once they are out there, it spreads like a virus,” police say.

Media
The American Academy of Pediatrics has argued that media representations of sexuality may influence teen sexual behavior, and this view is supported by many scholars,. Young teens who watch movies with more sexual content tend to become sexually active at an earlier age, and engage in riskier sexual behaviors.

The American media is the most sexually suggestive in the world. The sexual messages contained in film, television, and music are becoming more explicit in dialog, lyrics, and behavior. In addition, these messages contain unrealistic, inaccurate, and misleading information that young people accept as fact. In television programing aimed at teens, more than 90% of episodes had at least one sexual reference in it with an average of 7.9 references per hour.

“Few [films] showed contraceptive use or safe sexual practices. When safe sex is portrayed in films, it is often in comedies and is presented as an inconvenience or embarrassment. The motion picture industry could make an effort to show healthier, safer behaviors, just as they have reduced the amount of smoking shown in films. To minimize risky sexual behavior later in life, parents can restrict the amount of sexual content children view and educate them about the consequences of sexual behavior that are often left out of films.”

Some researchers have found a correlation between the amount of television with high sexual content that teenagers watch and an increased likelihood of them becoming pregnant or fathering a child out of wedlock. These researchers believe that reducing the amount of sexual content adolescents watch on television could substantially reduce the teen pregnancy rate.

Family
Dr Drew wants to make one thing "clear to parents out there. It is OK to tell your kids not to have sex. And I would encourage you to do so. Delaying is the goal here."

Researchers at Boston College have found that teens who frequently did “things like eating dinner together as a family or engaging in fun activities or religious activities together” were less likely to have sex, had fewer sexual partners, and had less unprotected sex. One additional family activity per week reduces the likelihood of sexual activity by 9%. Family activities were "centrally important supports for children, providing opportunities for emotional warmth, communication, and transmission of values and beliefs.” However, "negative and psychologically controlling" parenting such as "criticizing the ideas of the adolescents, controlling and directing what they think and how they feel," increased the probability of adolescents having sex.

Researchers at the University of Arizona, University of Texas-Austin and Wake Forest University have found that girls who have positive relationships with their fathers wait longer before they have sex. Other research shows that kids whose dads are involved report less sexual activity than on average, and less risky sexual behaviors when they do.

Girls who grew up in homes without their father are significantly more likely to have premarital sex than girls who are raised by both parents. In addition, teens who lived with stepparents or in a single-parent household had notably higher levels of risky sex behavior than did kids who lived in stable and biological-parent families. At a summit in Detroit on girls and sexual attitudes it was revealed that some "girls in that same age group [13–16] are 'dating' men as old as 30 because the men can give them things – love, money, presents – that their parents cannot."

The Patriot Ledger stated that in current times "Adults condone a variety of sexual misbehaviors, from harassment to assault" which can give a ones daughter or son the wrong idea about what is correct/acceptable and what is not when it comes to sex.

Friends
Both boys and girls feel pressure from their friends to have sex. The perception adolescents have of their best friends' sexual behavior has a significant association with their own sex behavior. Sexually active peers have a negative effect on adolescent sexual delay, however responsive parent-adolescent sex discussions can buffer these effects.

Adolescents who reported sexual activity had high levels of reputation-based popularity, but not likeability among peers; however, sex with more partners was associated with lower levels of popularity.

Sexual education
Two main forms of sex education are taught in American schools: comprehensive and abstinence-only. Comprehensive sex education covers abstinence as a positive choice, but also teaches about contraception and avoidance of STIs when sexually active. A 2002 study conducted by the Kaiser Family Foundation found that 58% of secondary school principals describe their sex education curriculum as comprehensive. The difference between these two approaches, and their impact on teen behavior, remains a controversial subject in the United States.

There have been numerous studies on the effectiveness of both approaches, and conflicting data on American public opinion. Public opinion polls conducted over the years have found that the majority of Americans favor broader sex education programs over those that teach only abstinence, although abstinence educators recently published poll data with the totally opposite conclusion. The poll sponsored by the National Abstinence Education Association and conducted by Zogby International found that:

"When parents become aware of what abstinence education vs. comprehensive sex education actually teaches, support for abstinence programs jumps from 40% to 60%, while support for comprehensive programs drops from 50% to 30%. This sharp increase in support of abstinence education is seen across all political and economic groups. The majority of parents reject the so-called 'comprehensive' sex education approach, which focuses on promoting and demonstrating contraceptive use. Sixty-six percent of parents think that the importance of the 'wait to have sex' message ends up being lost when programs demonstrate and encourage the use of contraception."

Experts at University of California, San Francisco also encourage sex educators to include oral sex and emotional concerns as part of their curriculum. Their findings also support earlier studies that conclude

"that sexual risk-taking should be considered from a dynamic relationship perspective, rather than solely from a traditional disease-model perspective. Prevention programs rarely discuss adolescents’ social and emotional concerns regarding sex.... Discussion about potential negative consequences, such as experiencing guilt or feeling used by one's partner, may lead some adolescents to delay the onset of sexual behavior until they feel more sure of the strength of their relationship with a partner and more comfortable with the idea of becoming sexually active. Identification of common negative social and emotional consequences of having sex may also be useful in screening for adolescents at risk of experiencing more-serious adverse outcomes after having sex."

Comprehensive
The National Association of School Psychologists, the American Academy of Pediatrics, the American Public Health Association, the Society for Adolescent Medicine and the American College Health Association, have all stated official support for comprehensive sex education. Comprehensive sex education curricula are intended to reduce sexually transmitted disease and out-of-wedlock or teenage pregnancies.

Proponents of this approach argue that sexual behavior after puberty is a given, and it is therefore crucial to provide information about the risks and how they can be minimized. They hold that abstinence-only sex ed and conservative moralizing will only alienate students and thus weaken the message.

A report issued by the Department of Health and Human Services has found the "most consistent and clear finding is that sex education does not cause adolescents to initiate sex when they would not otherwise have done so." The same report also found that:

Family life or sex education in the public schools, which traditionally has consisted largely of providing factual information at the secondary school level, is the most general or pervasive approach to preventing pregnancy among adolescents.... Adolescents who begin having sexual intercourse need to understand the importance of using an effective contraceptive every time they have sex. This requires convincing sexually active teens who have never used contraception to do so. In addition, sexually active teens who sometimes use contraceptives need to use them more consistently (every time they have sex) and use them correctly.

Abstinence-only
Abstinence-only sex education tells teenagers that they should be sexually abstinent until marriage and does not provide information about contraception. In the Kaiser study, 34% of high-school principals said their school's main message was abstinence-only. Some Christian organizations advocate abstinence-only sex education because it is the only approach they find acceptable and in accordance with their churches' teachings.

Some organizations promote what they consider to be "sexual purity", which encompasses abstaining from not only intercourse before marriage, but also from sexual thoughts, sexual touching, pornography, and actions that are known to lead to sexual arousal. Advocates of abstinence-only sex education object to comprehensive curricula which fail to teach moral behavior; they maintain that curricula should promote conventional (or conservative) morality as healthy and constructive, and that value-free knowledge of the body may lead to immoral, unhealthy and harmful practices.

A comprehensive review of 115 program evaluations published in November 2007 by the National Campaign to Prevent Teen and Unplanned Pregnancy found that two-thirds of sex education programs focusing on both abstinence and contraception had a positive effect on teen sexual behavior. The same study found no strong evidence that programs that stress abstinence as the only acceptable behavior for unmarried teens delayed the initiation of sex, hastened the return to abstinence, or reduced the number of sexual partners. According to the study author:

"'Even though there does not exist strong evidence that any particular abstinence program is effective at delaying sex or reducing sexual behavior, one should not conclude that all abstinence programs are ineffective. After all, programs are diverse, fewer than 10 rigorous studies of these programs have been carried out, and studies of two programs have provided modestly encouraging results. In sum, studies of abstinence programs have not produced sufficient evidence to justify their widespread dissemination.'"

Extracurricular activities
Girls who participate in athletics, artistic, or academic extracurricular activities are less likely to be sexually active than girls who don't participate in any. Female athletes have "significantly fewer sex partners, engaged in less frequent intercourse... and began having sex at a later age." For boys, those who participate in sports are slightly more likely to be sexually active, and those who are in artistic activities are considerably less likely.

Religion
Religious adolescents lose their virginity 3 years later than the average American. On average, those with strong religious backgrounds become sexually active at age 21. Many studies have found an inverse relationship between religiosity and high-risk adolescent behaviors, including sexual activity. Religion and family support can provide a positive model for adolescents.

On the other hand, violating a community's religious norms can evoke feelings of guilt, shame, and fear, and may provoke social sanctions from the community, including formal rebukes from clergy, as well as gossip, ridicule, and ostracism from peers. Avoidance of these consequences encourages conformity and abstinence in adolescents. Because of this form of social control, religious adolescents who do engage in sexual activity may experience increased cognitive dissonance and psychological distress. The inverse relationship between religiosity and high-risk behaviors in adolescents can in part be attributed to sexually active religious teens attempting reduce cognitive dissonance in one of two ways: either by reducing their sexual activity or by altering their religious beliefs to reduce conflict with their behavior. This therefore serves as a self-selection bias, where those more involved in religious communities may be those who are more risk-averse and comfortable with social control."

Sexual minorities
According to a study based on a sampling of teenagers in Massachusetts, sexual minority youth, that is, those who identify as gay, lesbian, or bisexual or had any same-sex sexual contact in their lifetimes, were significantly more likely than other students to report lifetime sexual intercourse (72% vs. 44%). The same study found that sexual minority youth were more likely to report sexual intercourse before age 13 (18% vs. 4%), sexual intercourse with four or more partners in their lifetimes (32% vs. 11%), and recent sexual intercourse (55% vs. 33%). Among students in the Massachusetts study who ever had sexual intercourse in their lifetimes, sexual minority youth were significantly more likely than other students to report "having been or gotten someone pregnant (15% vs. 4%) and having been diagnosed with HIV or another STI (10% vs. 5%)."

Several studies have found that gay youths are represented disproportionately among adolescents who drop out of school, run away from home, abuse alcohol and other drugs, engage in prostitution, or attempt, contemplate and successfully commit suicide.

Knowledge of sexuality
Most teens (70%) say they have gotten some or a lot of information about sex and sexual relationships from their parents. Other sources of information include friends at 53%, school, also at 53%, TV and movies at 51% and magazines at 34%. School and magazines were sources of information for more girls than boys, and teens "who were sexually active were much more likely to say they got information about sex from their friends and partners."

Less than half of parents with daughters under 18 talk to their girls about how to say no to boys, and about half talk to them about contraception. While 78% of parents believe that their daughters can talk to them about any topic, only 54% of girls believe they can discuss any topic with them.

Correlation with other risk behaviors
According to a report prepared for the U.S. Department of Health and Human Services,

the younger the age of first sexual intercourse, the greater the risk of unwanted pregnancy and sexually transmitted infections. This is because those who begin having sex at young ages are generally exposed to risk for a longer time, are less likely to use contraception, generally have more sexual partners, and tend to engage in higher risk sexual behaviors such as alcohol or drug use prior to sexual intercourse and having multiple concurrent sexual partners. It must be recognized as well that early intercourse is frequently not voluntary.

Less than 20% of teens become sexually active at 14 years of age or younger; however, if they do, they are six times more likely than their peers that self-identify as a virgin to drink alcohol once a week or more, four times more likely to have smoked marijuana and three times more likely to be regular smokers of cigarettes. Other research also shows that risk behaviors often appear in clusters. If an adolescent is engaging in one risk behavior then there is a strong chance there may be others. For example, many teens are either using drugs or alcohol when they first have sexual intercourse. Students seventh and eighth grade who use drugs and alcohol were more likely than non users to begin having sex.

Researchers have also found that the younger an adolescent is at the time of their sexual debut, the greater the likelihood that they will engage in delinquent acts later. Adolescents who experience late sexual debut are the least likely to participate in delinquency. According to one of the study's co-authors, Dana Haynie, adolescents who start having sex at a young age may not be prepared to deal with the emotional, social and behavioral consequences of their actions. Study coauthor Stacy Armour theorized that adolescents "who waited longer than average may be developing friendships and relationships that can help protect them from potentially troublesome behaviors as they become young adults...The timing of events such as sexual activity can have profound consequences for adolescents, particularly when they occur prematurely...[T]he timing of sexual initiation does matter. Adolescents need to be at a stage when they are developmentally prepared for it."

Girls who participate in group sex are more likely to smoke cigarettes, get an STD, and be victims of dating violence.
