Well if it was in a threesome I would not stop him, but one on one would not be that much of a turn-on for me. There is also the wife thing, if she doesn't know I wont do it. Ii have had mfm with friends and their wives but this has never come up with them but that was a long time ago. My wife knows about the past and knows I'd like to get back into the life as she is all for it but time is not on our side
