Maybe it's a cultural thing. I don't see how it is too big of a deal for a man to visit a prostitute. Maybe your wife would feel better if she knew you were visiting many different prostitutes and not just one. If you are just going to the same one over and over, it is like a second wife you are supporting. That's definitely cheating, especially if you do not have the finances to afford it. Maybe you should let your wife know that you are not planning to abandon her for this prostitute and you are not planning to take care of this prostitute as another wife; you are only doing it for sexual gratification.
