Group sex is sexual behaviour involving more than two participants at the same time. The main focus of this page is group sex among humans; however, group sex also exists with other species in the animal kingdom -- e.g., bighorn sheep and bonobos.
Any and all sexual behaviour performed by two people can be a part of group sex, as well as a number of behaviors only possible with more than two people. Group sex involving one participant being penetrated by multiple people is sometimes termed a gang bang.
The same safe sex considerations that apply to one-on-one sex apply to group sex, for the same reasons. People who have group sex may have higher numbers of sexual partners, and may for this reason be more likely to have sexually transmitted infections (STIs) or to be at risk for STIs than those who have fewer sexual partners. Group sex can occur amongst people of all sexual orientations and genders.
Group sex may involve three or more people of any gender or sexual orientation. The events themselves may be characterized by sex; for example, a straight group sex session would involve only heterosexual sex. Some venues for group sex may be intended for a particular group or groups of people; for example, many sex parties in the United States are restricted to women or couples and it's in these parties homosexual contact between women is common. In the gay male community, there are nightclubs, bath houses, and internet groups that organize and participate in group sex. Different types of group sex may or may not involve switching partners. Some sex clubs, for example, require entrants to come in pairs and do not typically involve actual physical contact between people in different pairs. Group sex may involve a specific set of sexual activities; for example, some involve BDSM, while "tobylove" and "vanilla" group sex does not. (read more . . . )
