Fellatio (also known as fellation, and in slang as blowjob, BJ, giving head, or sucking off) is an oral sex act consisting of the stimulation of a penis by using the mouth. Oral stimulation of the scrotum may also be termed fellatio, or colloquially as teabagging.
It may be performed by a sexual partner as foreplay before other sexual activities, such as vaginal or anal intercourse, or as an erotic and physically intimate act of its own. Fellatio creates a risk of contracting sexually transmitted infections (STIs), but the risk is significantly lower than that of vaginal or anal sex, especially for HIV transmission.
Most countries do not have laws banning the practice of fellatio, though some cultures may consider it taboo. People may also refrain from engaging in fellatio due to personal preference, negative feelings, or sexual inhibitions. Commonly, people do not view oral sex as affecting the virginity of either partner, though opinions on the matter vary.
