Yes, they do happen. The majority usually fall into the category of "weird old fat people getting their freak on" at someones house in the suburbs (which would probably be a bad scene), but there are also cool "swinger/alt lifestyle" networks that hold club party's on occasion.
We've held many swinger party's at the clubs I work at, and it's a great time. These are always private invite only events, and getting an invite is a complicated process. The organizations we've worked with are great, and the customers high class.
You need to connect with a "swinger network". That's pretty much what it comes down to. Oh, and if you're a guy, you're gonna need a hot girlfriend/wife/escort with you to get through the door.
That's how it works. Have your Beer Goggles ready though, there's always the "Why the fuck is that person naked?!" moments at these events. lol
:surprise:
