I just heard about this the other day. I can't imagine why a guy would want to watch his wife/girlfriend have sex with another guy right in front of him. That is so messed up I don't know where to begin. I mean I would never ever want my significant other to have sex with anyone else let alone do it right in front of me. Maybe I am missing something. As for girls: Why would you bother being with someone if your going to have sex with other men anyway? Any thoughts?
