Anal sex (also called anal intercourse) is the sex act in which the penis is inserted into the anus of a sexual partner. The term can also include other sexual acts involving the anus, including pegging, anilingus, fingering, and object insertion.

While anal sex is commonly associated with male homosexuality, research shows that not all gay males engage in anal sex and that it is not uncommon in heterosexual relationships. Types of anal sex can also be a part of lesbian sexual practices.

Many people find anal sex pleasurable, and some may reach orgasm — through stimulation of the prostate in men, and clitoral and G-Spot leg stimulation in women. However, many people find it painful as well, sometimes extremely so, which may be psychosomatic in some cases. As with most forms of sexual interaction, individuals are at risk for contracting sexually transmitted diseases, and therefore safe-sex practices are advised. Anal sex is considered a high-risk sexual practice, and unprotected anal sex is the riskiest of all forms of sexual intercourse, due to the vulnerability of the rectum and sphincter tissues. It generally requires a generous application of a personal lubricant to prevent tearing, since the anus does not have sufficient natural lubrication.
