In human sexuality, a '''threesome''' is "a sexual interaction between three people whereby at least one engages in physical sexual behaviour with both the other individuals".<ref name=":0">{{Cite book|last=Scoats|first=Ryan |title=UNDERSTANDING THREESOMES: gender, sex, and consensual non-monogamy |date=2019|publisher=ROUTLEDGE|isbn=978-0-429-84237-5 |oclc=1110711748}}</ref> While the term ''threesome'' typically refers to sexual activity involving three participants,<ref name=":0" /><ref>{{Cite journal|last1=Thompson|first1=Ashley E.|last2=Byers|first2=E.

A threesome is a form of group sex that typically occurs in private settings, such as spontaneous sexual activity among three friends or in the context of casual sex or a hook up. A threesome may occur in specific contexts or environments that allow for sex, such as swingers events, orgies, or sex parties.{{fact|date=January 2024}} Threesomes are a common element of sexual fantasy,<ref>{{Cite book|last=LEHMILLER|first=JUSTIN J.|title=TELL ME WHAT YOU WANT: The Science of Sexual Desire and How It Can Help You Improve Your Sex Life |date=2018|publisher=ROBINSON|isbn=978-1-4721-4223-8|oclc=1013584575}}</ref><ref>{{Cite journal|last1=Jonason|first1=Peter K.|last2=Marks|first2=Michael J.|date=March 2009|title=Common vs. Uncommon Sexual Acts: Evidence for the Sexual Double Standard|url=http://link.springer.com/10.1007/s11199-008-9542-z|journal=Sex Roles|language=en|volume=60|issue=5–6|pages=357–365|doi=10.1007/s11199-008-9542-z|s2cid=53548047|issn=0360-0025|url-access=subscription}}</ref> and are widely depicted in pornography.

== Types == The people in a threesome may be of any gender and sexual orientation. Each participant may engage in any type of sex act with one or both of the others, such as vaginal, anal, oral, or manual sex. One or more of the participants may engage in autoerotic sexual activity, such as masturbation, 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 as voyeurism or cuckolding or cuckqueaning. Troilism is a term that encompasses both threesomes and cuckoldry, although its usage across literature is inconsistent.<ref>{{Cite book|last=Ley|first=David J.|title=Insatiable wives: women who stray and the men who love them|date=2009|publisher=Rowman & Littlefield|isbn=978-1-4422-0030-2|location=Lanham, Md.|oclc=373474387}}</ref>

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).<ref name=":0" />

''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.

== Academic research == The first major academic work to address threesomes specifically was published in 1988, called: ''Threesomes: Studies in Sex, Power, and Intimacy''<ref>{{Cite book|last=Karlen|first=Arno |title=Threesomes: studies in sex, power, and intimacy|date=1988|publisher=Beech Tree Books |isbn=0-688-06536-8|location=New York|oclc=17104896}}</ref> by Arno 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:

<blockquote>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.</blockquote>

Research exploring rates of threesome engagement suggest that men have both higher levels of interest and participation in threesomes.<ref>{{Cite journal|last1=Thompson|first1=Ashley E.|last2=Cipriano|first2=Allison E.|last3=Kirkeby|first3=Kimberley M.|last4=Wilder|first4=Delaney|last5=Lehmiller|first5=Justin J.|date=2020-11-11|title=Exploring Variations in North American Adults' Attitudes, Interest, Experience, and Outcomes Related to Mixed-Gender Threesomes: A Replication and Extension|journal=Archives of Sexual Behavior|volume=50|issue=4|pages=1433–1448|language=en|doi=10.1007/s10508-020-01829-1|pmid=33175272|s2cid=226302189|issn=1573-2800}}</ref> 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.<ref>{{Cite journal|date=1987-01-01|title=Male-female differences in sexual activity, enjoyment and fantasies|url=https://www.sciencedirect.com/science/article/abs/pii/0191886987900195|journal=Personality and Individual Differences|language=en|volume=8|issue=1|pages=125–127|doi=10.1016/0191-8869(87)90019-5|issn=0191-8869|last1=Wilson|first1=Glenn D.|url-access=subscription}}</ref> 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.<ref>{{Cite journal|last1=Herbenick|first1=Debby|last2=Bowling|first2=Jessamyn|last3=Fu|first3=Tsung-Chieh (Jane)|last4=Dodge|first4=Brian|last5=Guerra-Reyes|first5=Lucia|last6=Sanders|first6=Stephanie|date=2017-07-20|title=Sexual diversity in the United States: Results from a nationally representative probability sample of adult women and men|journal=PLOS ONE|language=en|volume=12|issue=7|article-number=e0181198|doi=10.1371/journal.pone.0181198|issn=1932-6203|pmc=5519052|pmid=28727762|bibcode=2017PLoSO..1281198H|doi-access=free}}</ref>
