In another thread, the OP starts off with the premise, "the male fantasy of wishing their wife/girlfriend to have sex with another man is fairly common". Common? I may be just a babe in the woods, and I do know that the fantasy does exist (there probably isn't any fantasy involving sex that doesn't exist somewhere, in some man's mind) but I never thought of this one as "common". I think I have a reasonably active imagination when it comes to sexual fantasies, but I have to say that this one has never entered my mind. (Now, her having sex with other women... well, don't get me started!) In fact, trying right now to imagine my girlfriend having sex with another man, is something I can only describe as dispiriting and depressing. But, to each his own. I'm just wondering how common this fantasy is among men. And for those who do enjoy such a fantasy, is observing the act an essential part of it? Would her doing it behind closed doors, then coming home and dutifully describing the experience to you, be a turn on?
