Fellatio
Fellatio (also known as fellation,[1] and in slang as blowjob, BJ, giving head, or sucking off)[2] is an oral sex act consisting of the stimulation of a penis by using the mouth.
The essential aspect of fellatio is oral stimulation of the penis (including the shaft and glans) through sucking with the mouth, use of the tongue for licking, using the lips, or some combination.
[8] One method is the sex partner taking the penis into the mouth and moving smoothly up and down to a rhythm while being careful to avoid contact with the teeth.
[19] It is physically possible for men with sufficient flexibility, penis size, or both, to perform fellatio on themselves as a form of masturbation, in an act called autofellatio.
As late as 1976, some doctors were advising women in the eighth and ninth months of pregnancy not to swallow semen lest it induce premature labor, but it was later determined to be safe.
The male may position his penis prior to ejaculation so that semen will be deposited onto his partner's face (known as a "facial"), or other body part such as their neck, chest or breast.
[11][12][32] Brushing the teeth, flossing, or undergoing dental work soon before or after giving fellatio can also increase the risk of transmission, because all of these activities can cause small scratches in the lining of the mouth.
Because of the aforementioned factors, medical sources advise the use of condoms or other effective barrier methods when performing or receiving fellatio with a partner whose STI status is unknown.
The potentially fatal complication pre-eclampsia was observed to occur less in women who regularly engaged in fellatio, with those who also ingested their partner's semen being at the least risk.
[38] The results were consistent with the fact that semen contains TGF-β1, the exchange of which between partners has a causal reduction in risk of pre-eclampsia caused by an immunological reaction.
Under Malaysia's Section 377A of the Penal Code, the introduction of the penis into the anus or mouth of another person is considered a "carnal intercourse against the order of nature" and is punishable with imprisonment of 20 years maximum and whipping.
[46] Galienus called fellatio lesbiari since women of the island of Lesbos were supposed to have introduced the practice of using one's lips to give sexual pleasure.
However, according to the Kama Sutra, fellatio is above all a characteristic of eunuchs (or, according to other translations, of effeminate homosexuals or trans women similar to the modern Hijra of India), who use their mouths as a substitute for female genitalia.
The author appears to somewhat agree with these attitudes, claiming that "a wise man" should not engage in that form of intercourse while acknowledging that it can be appropriate in some unspecified cases.
[53] In some cultures, such as Cambodia, Chinese in Southeast Asia, northern Manchu tribes along Amur River,[54] Sambians in Papua New Guinea, Thailand, Telugus of India, Native Hawaiians and other Pacific Islanders, briefly taking the penis of a male infant or toddler into one's mouth was considered a nonsexual form of affection or even a form of ritual, greeting, respect, parenting love, or lifesaving.
[59][60] It has also been reported that some modern Chinese mothers have performed fellatio to their moribund sons as affection and means for lifesaving, because they culturally believe that when the penis is completely retracted into the abdomen, the boy or man will die.
[63][66] Male Livingstone's fruit bats have been observed engaging in homosexual fellatio, although it is unknown if this is an example of sexual behavior or social grooming.
