How do you define adultery? To my mind, the traditional Jewish definition is horrifically sexist--to the point of treating women like chattel. A woman commits adultery if she's married and has sex with someone other than her husband. A man commits adultery if he has sex with another man's wife. It doesn't work the other way. A married man can have sex with an unmarried woman without either of them breaking religious law. And what about Christianity? According to Matthew 5:28--the quote that launched the big "Bible and Risqué Films" discussion on this forum--the mere emotional response of feeling lust for a woman is adultery. It doesn't say anything about anyone being married. Not to attack someone else's religion (of course, I just attacked my own), but the idea of "committing adultery in your heart" makes no sense to me. It's what you do that's right or wrong, not what you think. At least that's my view. To my mind, adultery is about being dishonest about your sexual activity. You're telling your spouse (or significant other) that they are your only lover, when in fact they are not. And to my mind, that's very wrong indeed.
