Traditionally, intercourse has been viewed as the natural endpoint of all sexual contact between a man and a woman,[2] and is commonly confined to this definition today. The meaning of the term, however, has been broadened in recent years, and now labels at least three different sex acts. These three types of intercourse are: vaginal intercourse, involving vaginal penetration by the penis; oral intercourse, involving oral caress of the sex organs; and anal intercourse, involving insertion of the male's penis into his partner's anus.[2]
