This is a tough one to answer. I would like to, but not sure how I would feel seeing my wife having sex with another guy. It'd be easier if it was my wife and another woman but still, I'd feel like I was cheating on my wife with the other woman. If we did have a MFF threesome the other woman would have to be a special friend to take part, no strangers. However, my wife has told me she has no interest in having sex with other woman.

If we wanted to have different partners than a MMFF would be our preferred choice, but how we would feel afterwards is a difficult question to answer.
