I voted no, I know my wife has cheated on me with at least two guys, probably another two, and maybe another two on top of that. One of the guys she isn't aware that I know about it, one of them she does know. It did cause a bit of friction for about a day, and although I couldn't quite bring myself to tell her how much her cheating turned me on I did let her know that I wasn't that bothered about it.
