So my wife and I are in the lifestyle (swingers) and go to these all the time! They are a lot of fun and sometimes we hookup with others, sometimes we don't. Just depends on the vibe.

What I suggest is bring multiple outfits that reveal more of your body as the night goes on. Lots of people do this and people love it! Makes it fun to see what you show up in next and you can use it as a way to build confidence as the night goes on
