“Most of the couples that are there — not all of them — but most are in some type of an open relationship, which used to be called “swingers.” That nomenclature has changed over the years. It’s definitely not exclusive to swingers. And the umbrella name of “swinger,” that definition is really changing. In the ’70s, I think people thought of swingers as exchanging, swapping couples, for sex. Today, it can be couples that enjoy having threesomes or just like to be around other couples when they’re having sex. It also reaches people that just like the sexy atmosphere of clubs that cater to people that are curious about the lifestyle.” https://www.insidehook.com/article/sex-and-dating/john-melfi-colette-swingers-clubs-interview
