Human sexual activity is generally influenced by social rules that are culturally specific and vary widely.<ref name="EUAB">{{Cite book|url=https://books.google.com/books?id=ybIaCgAAQBAJ&pg=PT386|title=Essentials of Understanding Abnormal Behavior|isbn=978-1305854703|publisher=Cengage Learning|last1=Sue|first1=David|last2=Sue|first2=Derald Wing|last3=Sue|first3=Diane M|last4=Sue|first4=Stanley|date=2016|page=352}}</ref>

Sexual ethics, morals, and norms relate to issues including deception/honesty, legality, [[fidelity]] and consent. Some activities, known as [[Sex and the law|sex crimes]] in some locations, are illegal in some jurisdictions, including those conducted between (or among) consenting and competent adults (examples include [[sodomy law]] and adult–adult [[incest]]).

Some people who are in a relationship but want to hide polygamous activity (possibly of opposite sexual orientation) from their partner, may solicit consensual sexual activity with others through personal contacts, [[online chat room]]s, or, advertising in select media.

[[Swinging (sexual practice)|Swinging]] involves singles or partners in a [[committed relationship]] engaging in sexual activities with others as a [[recreational sex|recreational]] or social activity.<ref name="MATF">{{Cite book|url=https://books.google.com/books?id=xVKWDwAAQBAJ&pg=PT287|title=Marriage and the Family: Mirror of a Diverse Global Society|isbn=978-1317279846|publisher=Routledge|last1=Xuemei Hu|first1=Julie|last2=Tarrezz Nash|first2=Shondrah|date=2019|page=287}}</ref> The increasing popularity of swinging is regarded by some as arising from the upsurge in sexual activity during the [[sexual revolution]] of the 1960s.

Some people engage in various sexual activities as a business transaction. When this involves having sex with, or performing certain actual sexual acts for another person in exchange for money or something of value, it is called prostitution. Other aspects of the [[Sex industry|adult industry]] include [[phone sex]] operators, [[strip club]]s, and pornography.
