Anal sex is a form of sexual intercourse where the penis is inserted into the anus of a sexual partner. This form of sex is common in both gay and straight relationships.
Although some people view anal sex as taboo, it can be enjoyable for couples if practiced with care. Both men and women have many erotic nerve endings in their anal area, and anal sex is just another way for consenting adults to add some extra spice to their sex life.
Anal sex may also be known as butt sex or rectal sex.
