My wife and I tried it together and alone . It really didn't do it for us, but thats us. We have been married a long time so we don't have sex nearly as much as we used to but it still is as hot as ever, we go out of our way to please each other , I make sure she has multiple orgasms ( I love to watch her have em too)and I can do anything I want (within reason). The key is we try to please the other partner, this is vital in my mind. Next time you do have sex with her , try to make it about her, you'll have an orgasm , us guys ALWAYS do. Try using toys (vibrators, dongs etc. she might have a few already)watch her moan, it's really hot.Cyber, if you feel bad then it's probably cheating but I wouldn't call it adutery.
