I'll chime in here, if I may..
My experience with swingers clubs is limited to Toronto, but I have reason to believe it'd be the same anywhere.
The experience for single men is much, much different than that for single women or couples. While single women tend to be welcomed with open arms, single men are almost actively discouraged from attending (higher fees, completely different set of rules..). The fantasy of an average looking single guy going to a swingers club and hooking up with hot women really is just that - a fantasy. For sure, there are exceptions that prove the rule.. but IMHO, swingers clubs are more trouble than they're worth for single guys.
