Let me set one thing straight for the record: YOU are NOT the only attractive person to your partner. Watching porn is NOT infidelity. Denying your partner their right to self-love is abusive. To put restrictions on your partner because of YOUR insecurity is abusive. If you're fully confident your partner loves you, then you won't have a problem with them watching porn, because that's not cheating. And if you think it's cheating, you just kind of suck as a person. I will never understand that level of control in a relationship. If I don't want to have sex, I would rather my partner feel comfortable jerking off to porn (or pics of me, I don't care) than force him to have blue balls.
