Me and the wife have had sex in front of another couple. That's about it. I'd like to get involved in a group setting much like what you're describing Red. She's not totally oppossed to it, but she wants it to be with people she knows. We have the same problem that most of our friends are vanilla. Go figure.
I didn't like lovevoodo because it wants to charge right away. Personally, I found
