Mating press

Mating press is a sex position that usually consists of the man furiously thrusting downwards towards the woman, often holding her legs down or around the head. While the act has been practiced in many countries, it is mainly associated with Japanese sex culture where the term was created and the act was popularized.

Etymology
The name is derived from the Japanese word 種付けプレス, which is made up of tanetsuke (種付け), which means "mating", and puresu (プレス) which is the English word "press" in katakana. The word was first coined by mangaka Takatsu Keita.

Practice
The act has been performed in some shape and form in various countries throughout history although without a name. Since then, the act and name have been associated with Japan and credited with popularizing the act. The name and term have become popular outside of Japan thanks in part to the popularity of hentai and Japanese pornography. The term was only mainly used in pornographic manga and eventually expanded to real pornography. The term was mainly used as an online meme outside of Japan but eventually came to be used more often in outside pornographic industries too.
