One can live having their own mental health disorders, and simultaneously have a semblance of functionality in relationships.
It's not up to him, too sooth your internal struggles, at the same time, sensitivity to your struggles whilst maintaining his own core person needs to be possible.
Pornography can be a heated topic of debate, most everywhere, so I am not going to personally find myself concerned that he is watching this, not in front of you, and that you have body dysmorphia. Imo, both aspects can be compromised.
Going through his history, isn't going to resolve anything, breaches courtesy of privacy.
What needs to be addressed is inattentiveness in the bedroom.
Has he built up resentment towards you? Hence a withholding of craved and humanly needed intimacy? The act of sex, won't breed closeness. Some resent it, as a tool to give a false sense of closeness, in a fight and make up cycle.
There's a plethora of things that could be going on here.

Guess, to me, porn is a self gratification tool for many. So, why is he choosing self gratification over mutually consensual intimate relations with the woman he professes to love and cherish?
