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.

69 or sixty-nine is a sex position in which two people align themselves so that each person's mouth is near the other's genitals, allowing each partner to simultaneously perform oral sex on the other. The participants are thus mutually inverted like in the number 69, hence the code name. In this case, the numerals 6 and 9 are treated more as pictographic symbols than as numerical representations, with the bulbous part representing the heads of the performers.

A sex position is a positioning of the bodies that people use to engage in sexual intercourse or other sexual activities. Sexual acts are generally described by the positions the participants adopt in order to perform those acts. Though sexual intercourse generally involves penetration of the body of one person by another, sex positions commonly involve non-penetrative sexual activities.

Cunnilingus is an oral sex act consisting of the stimulation of a vulva by using the tongue and lips. The clitoris is the most sexually sensitive part of the vulva, and its stimulation may result in a woman becoming sexually aroused or achieving orgasm.
