Sexual intercourse or coitus is the human form of copulation. In a wider context, the term sexual intercourse may refer to a wider range of sexual activities than the term coitus, which usually only refers to vaginal intercourse. See human sexual behavior for a discussion of the broader sense of sexual intercourse.

Sexual intercourse may be preceded by foreplay which leads to sexual arousal of the partners, resulting in erection of the penis and natural lubrication of the vagina. The erect penis is inserted into the vagina and one or both of the partners move back and forth to stimulate themselves and each other usually to the point of ejaculation and orgasm. A detailed description of the physiology of sexual arousal and orgasm can be found in the article Human sexual response cycle.
