Thanks for the replies.
My permisteral preference is, like hando, to preted to be clueless but actually knowing everything.
Sometime ago my wife and I went to some dance classes and one night, while I was on business trip, she fucked one of the guys from the group. She told him we were married and that I was ok with it.
Nevertheless it was always quite unconfortable for both him and me to meet at the club. I think it is an unsual situation and most people don't know how to behave. We would say "hi" to each other but never went beyond that. He would probably feel threathen if I asked "well, did you enjoy fucking my wife?"
Now I would rather try the role of the "clueless husband" and see how it goes.
I think I would enjoy the look they would give me knowing that they fuck my wife and I don't know anything about it
The best is if she starts getting a reputation of a good and easy fuck.
Unfortunately, ending up on my knees in the shower floor sucking the cocks my wife would later on fuck would be too much to ask
