Extropervert

The word extropervert combines the terms extrovert, which is defined as a person who is energized by being around other people, and perversion, which is a type of human behavior that deviates from societal norms, typically in a sexual way. By combining the 2 terms, we come up with a person or people who get off being in sexually charged group situations.

I visited this swinger club called Sweet Cheeks, where I partied with the sexiest group of extroperverts that I have ever seen.
