Female performing fellatio

Fellatio (also known as fellation,^[1] and in slang as blowjob, BJ, giving head, or sucking off^[2]) is an oral sex act involving the use of the mouth or throat, which is usually performed by a person on the penis of another person. If performed on oneself, the act is called autofellatio.^[3][4] Oral stimulation of the scrotum may also be termed fellatio,^[5][6] or colloquially as teabagging.^[7]

Fellatio can be sexually arousing for both participants, and may lead to orgasm for the receiving partner.^[3][4] It may be performed by a sexual partner as foreplay before other sexual activities (such as vaginal or anal intercourse),^[3][8] or as an erotic and physically intimate act in its own right.^[3][4] Like most forms of sexual activity, oral sex creates a risk of contracting sexually transmitted infections (STIs/STDs). However, the transmission risk for oral sex, especially HIVtransmission, is significantly lower than for vaginal or anal sex.^[9][10][11]

Most countries do not have laws that ban the practice of oral sex, though some cultures may consider it taboo.^[3] People may also have negative feelings or sexual inhibitions about giving or receiving oral sex; they may refuse to engage in it of their own volition.^[3] Commonly, people do not regard forms of oral sex as affecting the virginity of either partner, though opinions on the matter vary.^{[12][13][14][15]}
