Fellatio

Fellation is also called a blowjob

Fellatio, also called a blowjob, giving head or sucking off, is when the penis of a person is stimulated by mouth, tongue, or teeth of another, often until orgasm though it can be as foreplay or revival after an orgasm. Oral stimulation of the scrotum may also be termed fellatio.

If performed upon oneself the act is termed Autofellatio.

The essential aspect of fellatio is for the sex partner to take the penis into their mouth, and then move their mouth up and down the penis to a rhythm set by them mimicking the thrusting motion of vaginal or anal intercourse, with saliva acting as a lubricant, and being careful not to bite or scratch with the teeth. Though a little nibbling might be okay. The man receiving fellatio can slow the rhythm of the stimulation by holding his partner's head. The partner may also orally play with the penis by licking, sucking, kissing or otherwise playing with the tongue and lips. Fellatio may also include the oral stimulation of the scrotum, whether licking, sucking or taking the entire scrotum into the mouth.

Often a person's natural gag reflex can make it difficult to perform Fellatio, though this can be suppressed with practice.

Deepthroating occurs when a person takes the entire penis into their mouth and throat. The technique and term were popularized by the 1972 pornographic film Deep Throat. For deep-throating, the penis has to be long enough so that it can reach the back of the recipient's throat. Deep-throating can be doubly difficult for someone with a sensitive gag reflex.

In porn a lot of emphasis is given to the act of the receiving partner swallowing the sperm should the man ejaculate; this is a reflection of the male view of the subject - that fellatio is a form of intimacy and spitting is a form of rejection.

Facefucking is not a form of fellatio, instead termed irrumatio, where the giving partner thrusts into the receiving partners mouth.
