I got more clarification just now.
He apparently won't be seeing a sex therapist, but actually a regular therapist who happens to deal with porn addiction.
I think that may be the culprit

I have no idea how to help...
I know I should not be thinking this way but it really messes with my self-esteem, thinking to myself that he'd much rather watch a bunch of naked girls in porn than do things with me...which I know ultimately isn't true.
Really hoping this gets better.
