I think one big problem with porn is that people equate sex to love. Two different things. Love enhances sex but is not a precursor.

If sex is taking a back seat to porn in a relationship then there is a problem. Otherwise, what is the problem? Jealousy? Fear? Low self esteem? It would seem to me that in cases like this, porn is not the problem, it just brings the problem out.

I agree that if a person wishes their partner not watch porn, there needs to be a respect for said partners wishes BUT, what about the porn watching partners wishes?
