Orgy

Participation in an orgy is a common sexual fantasy, and one that appears often in pornography. A 2015 survey found that 6% of women and 12% of men had engaged in group sex in their lifetime, but fewer than 3% of both genders had done so in the past year, suggesting group sex may not be a common occurrence.

The term orgy comes from the ancient Greek "orgia," which referred to an ecstatic form of cult worship. Because these cult rituals were secret and held at night, it was speculated that they involved sex, although this may not have been the case.
