Nope, but our neighbors are. It works for them (sort of ... uh) and as long as nobody gets hurt, what people want to do is fine by me. I say sort of because they have certain rules and invariably one of them messes up and breaks a rule and then the fight is on.

Personally, intimacy means too much to me emotionally to ever even consider it. I guess I'm one of those few guys that actually doesn't have any desire for multiple partners.
