==Types==
Sexual activity can be classified in a number of ways. The practices may be preceded by or consist solely of [[foreplay]].<ref name="EDHS">{{Cite book|url=https://books.google.com/books?id=8iarCwAAQBAJ&pg=PA545|title=Exploring the Dimensions of Human Sexuality|isbn=978-1284081541|publisher=Jones & Bartlett Publishers|last1=Greenberg|first1=Jerrold S.|last2=Bruess|first2=Clint E. Bruess|date=2016|page=545}}</ref> Acts involving one person ([[autoeroticism]]) may include [[sexual fantasy]] or [[masturbation]].<ref name="EDHS"/> If two people are involved, they may engage in vaginal sex, [[anal sex]], [[oral sex]] or [[Non-penetrative sex#Manual sex|manual sex]].<ref name="EDHS"/> [[Sexual penetration|Penetrative sex]] between two people may be described as [[sexual intercourse]], but definitions vary. If there are more than two participants in a sex act, it may be referred to as [[group sex]]. Autoerotic sexual activity can involve use of [[dildo]]s, [[Vibrator (sex toy)|vibrator]]s, [[butt plug]]s, and other [[sex toy]]s, though these devices can also be used with a partner.

Sexual activity can be classified into the [[gender]] and [[sexual orientation]] of the participants, as well as by the relationship of the participants. The relationships can be ones of marriage, [[intimate partner]]s, casual [[sex partners]] or [[anonymous sex|anonymous]]. Sexual activity can be regarded as [[conventional sex|conventional]] or as [[Kink (sexual)|alternative]], involving, for example, [[Sexual fetishism|fetishism]] or [[BDSM]] activities.<ref name="TAB">{{Cite book|url=https://books.google.com/books?id=7S7QUkNHb30C&pg=PT211|title=Therapy and Beyond: Counselling Psychology Contributions to Therapeutic and Social Issues|isbn=978-0470797587|publisher=John Wiley & Sons|last=Milton|first=Martin|date=2010|page=211}}</ref><ref name="SPSW">{{Cite book|url=https://books.google.com/books?id=n3TDDwAAQBAJ&pg=PT108|title=Sex-Positive Social Work|isbn=978-0231547666|publisher=Columbia University Press|last=Dodd |first=SJ|date=2020|page=108}}</ref>

Fetishism can take many forms, including the desire for certain body parts ([[partialism]]) such as [[Breast fetishism|breasts]], [[Navel fetishism|navels]], or [[Foot fetishism|feet]].<ref name="EFMT">{{Cite book|url=https://books.google.com/books?id=IGzWDwAAQBAJ&pg=PA272|title=Essentials of Forensic Medicine and Toxicology, 1st Edition|isbn=978-8131254585|publisher=Elsevier Health Sciences|last=Chand|first=Suresh|date=2019|page=272}}</ref> The object of desire can be [[Shoe fetishism|shoes]], [[Boot fetishism|boots]], [[lingerie]], [[Clothing fetish|clothing]], [[Leather subculture|leather]] or rubber items. Some non-conventional autoerotic practices can be dangerous. These include [[erotic asphyxiation|autoerotic asphyxiation]] and [[self-bondage]].<ref name="CCIBK">{{Cite book|url=https://books.google.com/books?id=wAN-DwAAQBAJ&pg=PA447|title=The Certified Criminal Investigator Body of Knowledge|isbn=978-1498752060|publisher=CRC Press|date=2017|page=447}}</ref> The potential for injury or even death that exists while engaging in the partnered versions of these fetishes (choking and [[Bondage (sexual)|bondage]], respectively) becomes drastically increased in the autoerotic case due to the isolation and lack of assistance in the event of a problem.<ref name="CCIBK"/>

Sexual activity that is consensual is sexual activity in which both or all participants agree to take part and are of the age that they can consent.<ref name="MSS">{{Cite book |last1=Cowling |first1=Mark |url=https://books.google.com/books?id=72NBDgAAQBAJ |title=Making Sense of Sexual Consent |last2=Reynolds |first2=Paul |date=2017 |publisher=Routledge |isbn=978-1351920711 |pages=1–304}}</ref> If sexual activity takes place under force or duress, it is considered [[rape]] or another form of [[sexual assault]]. In different cultures and countries, various sexual activities may be lawful or illegal in regards to the age, gender, [[Adultery laws|marital status]] or other factors of the participants, or otherwise contrary to [[social norms]] or generally accepted [[sexual morals]].<ref name="MSS"/>
