Group Sex
Group sex is sexual behaviour involving more than two people at the same time.
Any sexual behaviour performed as part of "conventional" two-person sex can be a part of group sex, as well as a number of behaviours only possible with more than two people. Group sex involving a single female or male and multiple males is sometimes termed a gang-bang.
The same safer sex considerations that apply to normal sex apply here, for the same reason: any sexual partner in any kind of sexual activity may have a sexually transmitted disease, without it being obvious, either to them or others. People who have group sex tend to have higher numbers of sexual partners, and may for this reason be more likely to have STDs or to be at risk for STDs than other people who have fewer sexual partners.
Group sex can occur amongst people of any sexual orientation, whether homosexual, heterosexual (though, obviously, sex involving three or more people must involve multiple members of the same gender in some capacity), bisexual or pansexual.
In human cultures, group sex is a common sexual fantasy, predating the existence of pornography, and participation in it is more common than some want to admit. Despite the puritanical taboo against sexual pleasure for its own sake, even prominent intellectuals such as Catherine Millet have admitted to frequent participation in group sex.
There is a misconception that group sex practices are confined to enactment for the purposes of pornography. Since pornography is often amateur (i.e. made for fun rather than money), it is obvious that the same practices are at least as common outside of pornography.
Sexual positions and combinations are possible only in group sex
Following is a list of possible group sex positions. They certainly can all be found in pornographic movies, though their widespread use in "real" life may be doubted:
* Spitroast: the simultaneous penetration of one person in the mouth and the vagina or anus. Sometimes called a wobbly H or (Chinese) finger cuffs, since the person in the middle is stuck between. (See also: Chasing Amy.)
* Double penetration: The simultaneous penetration of a woman's vagina and anus. Sometimes called a sandwich.
* Triple penetration usually refers to either two penises in the vagina and one in the anus, or two in the anus and one in the vagina.
* Airtight seal: the simultaneous penetration of a woman's vagina, anus and mouth. * Double vaginal penetration: the simultaneous penetration by two men of a single woman's vagina.
* Double anal penetration: the simultaneous penetration by two men of a single woman's or man's anus.
* DVDA, Double vaginal, double anal: the simultaneous penetration by two men of a single woman's vagina coupled with the simultaneous penetration by two men of the same woman's anus. There is no evidence that a DVDA has ever been accomplished as it is in all likelihood physically impossible.
* Daisy chain: a group of men simultaneously penetrating and being penetrated by each other anally in a chain formation; a group of men, women, or both, each performing oral sex on the next.
* Lucky Pierre: in which a man has vaginal sex with a woman, whilst himself being anally penetrated by another man—term can also be used for similar all-male activities.
These acts may also be performed by women wearing strap-on dildos.
Bukkake
Bukkake is a group sex practice seen in pornography where a series of men take turns ejaculating on a kneeling woman (or man). At the end of the process, the recipient usually drinks the semen. There is a misconception that bukkake is a recent invention of the fetish pornography industry. In fact, much of the bukkake pornography consists of amateur home movies made by people who enjoy the sex act on or off camera. Many women have gone public regarding their sexual enjoyment of bukkake. Prominent examples include Dr. Susan Block and Catherine Millet. Note that this is a potentially unsafe practice: see the bukkake article for more.
