Having sex with anyone other than your partner without their consent or knowledge is cheating no matter how you want to rationalize it.
You couldn't have put it any better Ric, we've had this topic many times before. It's sheer betrayal and total treachery to the one you're supposed to love. I'm afraid there's no going back. Having said that though, I can't stop myself punting, so I'll just have to settle with being a rat.
