What is the one theme that you can't conquer

Ive gotten over many themes. Even if they recycle at times, i have had long interruptions between to call them conquered. Some big (existential, contamination, pocd, etc) and some small (do i need to pee???, drinking water, etc). But holy shit i cant get over sexual ocd and checking if im perverted.

Pls no sex positive sexual liberation stuff in the comments. It does not help me. I just want to know what your experience is like
