ISO swinging clubs around Chicagoland area.

There's a different term they use here... not swinging or swapping, something unique. I wish I could remember what it was because then you'd be able to find their websites...

In any case, there are several groups but when I checked it out several years ago they basically don't accept single guys unless you already know someone inside and they vouch for you. It's mostly open to couples and single women. I guess that doesn't surprise me, since otherwise it would be a ridiculous sausage fest.

If you're into gangbang clubs, this might interest you.
