Anal sex

Anal sex or anal intercourse is a commonly practiced form of human sexual behavior in some cultures. It involves the anus (or rectum), especially, but not limited to, the insertion of the erect penis into the rectum through the anus. The use of sex toys and other activities involving the anus and rectum may be considered anal sex as well. Anal sex can be pleasurable for both the insertive partner and the receptive partner, as the anus contains many of the same kinds of nerves as the penis or clitoris (it can also be unpleasurable for both partners, especially if performed forcefully or without lubrication).
