I'm so sorry you're hurting. I don't know if I could imagine what it must feel like to be in your position.

Personally I despise porn and the porn industry. I don't see how any good can come from it. It's just not healthy. I can't wrap my head around how others allow their husbands and SO's to view it, but I digress...

I agree with lizardlady - it seems as though he is focused on his needs and yours are ignored. I think that asking for sex right after you have had a baby and are clearly in a lot of pain is quite selfish as well. Having you pose in positions you don't feel uncomfortable in is not okay.

Open discussion, as much as it might hurt and bring up painful feelings, would probably help a lot. If you think that just the two of you would have a hard time discussing, I see no problem with looking for a therapist to help facilitate! This sounds like a major problem in your relationship and you have a right to feel the way you're feeling.

Again, I'm so very sorry you're going through this.

Sending you hugs
