Is your ocd therapy resistant? You need a deep dive into your relationship with the human body and pleasure. If therapy isn't for you then it needs to be done independently.
You're ultimately having sex with a human, not a blow up doll. Humans have pleasant features but also flaws, veins, scars, scents, fluids, etc. We're sacks of flesh, it's kind of gross. We need to explore our relationship with that fact.
Not liking anal is fine though. I don't like it either and my sex life is fine.
I have this really deep phobia of the circulatory system. I hate everything about blood, veins, arteries, the heart, etc. All I can do is come to terms with it. It never fully goes away.
