Lesbian Sex Mafia

The Lesbian Sex Mafia (LSM) is an information and support group for bisexual women and lesbians interested in sexual activities involving BDSM, fetishes, costumes, etc. Founded in 1981 by Jo Arnone and Dorothy Allison, it is located in New York City.

The LSM works "to organize for [women's] sexual desire as strongly as we have tried to organize for our sexual defense". The name was deliberately chosen "in the same spirit of humor as the Ladies Sewing Circle and Terrorism Society."

History
The LSM organized a "Speakout on Politically Incorrect Sex" rally at the 1982 Barnard Conference on Sexuality. The group was also a subject of a documentary by the German filmmaker Monika Treut, Bondage, the first of four films in the Female Misbehaviour series.

In 1993, Pride Night by LSM, The Eulenspiegel Society, Excelsior MC, GMS/MA, and NLA: Metro New York received the Large Event of the Year award as part of the Pantheon of Leather Awards.

In 1996 LSM cofounder Jo Arnone received the National Leather Association International’s Jan Lyon Award for Regional or Local Work, in 2005 she received the Lifetime Achievement Award as part of the Pantheon of Leather Awards, and in 2010 she received the Mr. Marcus Hernandez Lifetime Achievement Award (Woman) as part of the Pantheon of Leather Awards.
