We had a nigt of fun with another couple,my wife and the other woman just could not get enough of each other(big turnon for me) the guy was about twice my size(a bit of a homopfobe),witch she also enjoyed.She knows that i am bi and wants to have a mmf 3some,but the idea of me and another man turns her off.No man has ever turned me on,but a penis does.I am not into anal sex,just oral.Why the double standards?
