Some seem to allow singles but others are couples only. I just did a google search of "sex clubs" along with my state and found a few sites that gave plenty of info on sex clubs in my area.
I actually live in the US. In many states the clubs are legal as long as they don't serve ******* and promote safe sex. The one we are considering going to has been open for six years.
The wife and I have been talking about it for a long time and found a local one that doesn't look too bad. Anyone have any experience with this kind of thing?
