Well I can contribute a little something to this topic. Years ago when I was married my wife had been talking with a girl from her work and she was sharing how her and her husband or boyfriend, I can't remember which, liked to watch porn and have kinky sex. My wife was talking about it for weeks as her friend was telling her stuff all along. My wife asked if I would be okay when her friend asked her to go hang with them one evening. I thought it was exciting and was turned on like crazy watching her get ready to go out. The problem was I did nothing over the next many hours but think what they must be doing. At fist being turned on then feeling left out as the hours clicked by. Had I been patient I was probably going to be included at some point but being young I got overcome by jealousy. I know something happened but ill never know what because I showed my inability to play along. I blurted out something I can't remember what but two sentences and it was undone.
