My biggest denial fantasy is becoming an anal-only slut, completely with body modification to have my clit permanently covered/removed and my vaginal canal and up removed. Even my inner and outer labia would be smoothed over, kind of like a Barbie doll. I would have been either tricked or forced into the surgery and then, afterwards, humiliated and degraded about how I would never cum again unless it was from my ass and how worthless a whore I am for not even having a cunt any more.
