I don't know, Pam, this does not sound like a porn addiction to me. AT ALL.

I think it is a case of a man turning to porn because he senses that his wife has no interest in him. THAT is a quite different situation from the original poster and does not constitute an addiction.

I would agree with you that if the porn bothers one person in the relationship, then it should be discarded but ONLY if the other person is willing to step up to the plate. You can't control his sexuality to that point--by saying, I won't have sex with you but I don't want you using porn either.
Can you see the unfairness in that statement?

What DO you want him to do?

In what way is it acceptable for him to express his sexuality?
