Blowjobs

Fellatio is oral sex performed on a male sexual partner. It involves the stimulation of the penis by the use of the mouth, tongue, teeth or throat.[1] The person whoperforms fellatio can be referred to as the giving partner, and the other person is the receiving partner. Fellatio is regarded by many as an erotic act in its own right and anintimate act. For many males, it is a turn-on which may be used by the giving partner to initiate foreplay and sexual arousal prior to sexual intercourse.[2] The act may alsobe performed for the sexual gratification derived by the male receiving partner and can be continued until orgasm and ejaculation of semen.
Fellatio is also sometimespracticed when sexual intercourse can create a physical difficulty for a sex partner. For example, it may be practiced during pregnancy instead of vaginal sex by couples wishingto engage in intimate sexual activity while avoiding the difficulty of vaginal intercourse during later stages of pregnancy.[3]
Some people have negative feelings or sexualinhibitions about giving or receiving oral sex, and may refuse to do so.[4] On the other hand, there are reports in the media from time to time that the practice is commonamong adolescent girls who fellate their boyfriends to create and maintain intimacy while preserving their virginity or avoiding pregnancy.[citation needed]
Some peopleregard the receiving partner as being in a position of psychological if not physical vulnerability, and thus is potentially weaker. Bringing a person to climax is considered bysome to be a form of exerting control over that person's physiology and emotions.
Fellatio is also known as fellation,[5] a blow job (BJ), giving head or sucking off.
