I don't think that masturbation by any partner, with porn, or just thinking about that cute secretary in the office, should be considered cheating. In a perfect relationship, you should be able to discuss this openly with your partner and work toward trying to share fantasies with each other.

Even President Jimmy Carter admitted to having "lust in his heart".

I do agree that hiding/lying is dishonest and wrong ... but I wouldn't call it cheating.
DonnieDarko Reviewed by DonnieDarko on . mental cheating??? what do you all think about porno in a commited relationship? I personally think it's "mental cheating" and while some might see that as too harsh, i believe the act of someone peeling one off to the image of another woman or man just isnt very cool...watching it together as a type of foreplay is fine, but to hide and lie about a stash is deceptive and wrong...guys and girls whats your opinion? how would your partners feel? is my opinion one of an oversensitive woman, or is it rational???
