While group sex is common as a fantasy, the actual prevalence of group
sex is unknown.
Some dismiss group sex as a phenomenon confined to pornography. This
is demonstrably false, as shown by the existence of various private
sex clubs that practice various forms of group sex. There are men and
women who openly recount their group sex experiences. Moreover, many
pornographic movies are simply documentary recordings of unscripted
sex acts performed as much for fun as for money. For example, a great
deal of homemade pornography fits this category. Group sex activity
appears in documentary pornography, such as homemade pornography produced
by erotic affinity groups.
