Group sex, also known as gang bang or orgy, refers to sexual activity involving three or more people engaging in various sexual acts with each other. This often includes a combination of penetrative and non-penetrative activities such as oral sex, mutual masturbation, and vaginal, anal, or oral intercourse. In pornography, group sex scenes typically involve a mix of genders and may also include elements of BDSM, roleplaying, or other kinks depending on the preferences and fantasies of the participants.
