{{main|Laws regarding incest}}
Sexual activity between family members or close relatives is often considered incest, which is illegal in many jurisdictions, though what constitutes an "incestuous relationship" varies by jurisdiction, and may depend on the type of sexual activity and whether the relationship is one of [[consanguinity]], [[Affinity (law)|affinity]] or other relationship, such as by adoption. In law, the proscribed sexual activity is usually limited to [[sexual intercourse]], though terminology varies, and which in some jurisdictions is limited to penile-vaginal sexual intercourse. Incestuous sexual activity, as defined by each jurisdiction, is usually unlawful irrespective of the consent of the parties and irrespective of their age. This prohibition usually also extends to the marriage of people in the proscribed incestuous relationships.

One author argued that use of particular language devices and rhetoric in the legislation surrounding these laws manipulates the viewer to automatically deem such sexual acts to be immoral and criminal. In this view, the law is attempting to morally control society, which is not one of the purposes of the law. This means that people will condemn those who partake in familial sexual activities, even if all parties are consenting adults.<ref>{{cite journal|title= The Synthetic Necessary Truth Behind New Labour's Criminalisation of Incest| doi=10.1177/0964663913502068 | volume=23|journal=Social & Legal Studies|pages=113–130|year = 2014|last1 = Roffee|first1 = James A.| s2cid=145292798 }}</ref>
