Inhuman sexuality, athreesome is "a sexual interaction between three people whereby at least one engages in physical sexual behaviour with both the other individuals".[1] While the termthreesome typically refers to sexual activity involving three participants,[1][2][3] it has at times been used to refer to a long-term domestic relationship, such aspolyamory or aménage à trois.[4]
A threesome is a form ofgroup sex that typically occurs in private settings, such as spontaneous sexual activity among three friends or in the context ofcasual sex or ahook up. A threesome may occur in specific contexts or environments that allow for sex, such asswingers events,orgies, orsex parties.[citation needed] Threesomes are a common element ofsexual fantasy,[5][6] and are widely depicted inpornography.
The people in a threesome may be of anygender andsexual orientation. Each participant may engage in any type of sex act with one or both of the others, such asvaginal,anal,oral, ormanual sex. One or more of the participants may engage inautoerotic sexual activity, such asmasturbation, possibly without physical contact with the other participants. It is a matter of subjective definition whether participation of a third person without physical contact constitutes a threesome and this sort of sexual activity might instead be interpreted asvoyeurism orcuckolding orcuckqueaning.Troilism is a term that encompasses both threesomes and cuckoldry, although its usage across literature is inconsistent.[7]
Threesomes are sometimes described using shorthand to refer to who was involved in the threesome e.g. MMF (male, male, female); FFM (female, female, male); MMM (male, male, male); FFF (female, female, female).[1]
Sandwich is slang for a person performing both receptive and insertive anal and/or vaginal sex simultaneously during a threesome, being positioned between the two partners.
The first major academic work to address threesomes specifically was published in 1988, called:Threesomes: Studies in Sex, Power, and Intimacy[8] byArno Karlen. In the work, drawing mainly from interview data, Karlen outlined how threesomes were often viewed as qualitatively different to other forms of group sex. Other notable findings include that threesomes were often viewed by women as a safe way to explore their sexuality; they often consisted of a couple joined by a third person; and that the third person was not necessarily viewed or treated equally. Karlen also suggested that the societal view of threesomes cast those who engaged in them as radically different to other members of society:
There is a common tendency to think of people who have been in threesomes as alien beings. Like swingers, homosexuals and others who deviate from basic sexual norms, they seem to many to have entered another social, psychological, and moral sphere.
Research exploring rates of threesome engagement suggest that men have both higher levels of interest and participation in threesomes.[9] One study soliciting responses to a sex survey via a British newspaper in 1987 found that 34% of 1,862 men, and 15% of 2,905 women had experience of a threesome.[10] From a nationally representative sample in the US in 2017, 34.1% of men and 11.1% of women found a threesome to be at least somewhat appealing and 18% of men and 10% of women had engaged in one.[11]
