Oral sex or oral intercourse is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth (including the lips, tongue or teeth) or throat. Cunnilingus is oral sex performed on a female, while fellatio is oral sex performed on a male. Anilingus, another form of oral sex, is oral stimulation of a person's anus. Oral stimulation of other parts of the body (as in kissing and licking) is usually not considered oral sex.
