You can't say he can't watch porn unless he can say you can't say no to sex?

This isn't a porn is right or wrong discussion. Today someone legitimately told me that women should not be allowed to tell their SO that they cannot watch porn unless he is allowed to tell them they can't tell him no when he wants sex. Do you agree or disagree?

I honestly believe it is our body and we have the right to decide whether or not someone has sex with it or touches it in any way, shape or form no matter your gender. I do NOT for one second believe saying no to porn is the same thing as saying no to sex. I don't believe anyone has the right to demand sex. Ever. Porn is something that should be discussed and decided on together before things get serious.
