Sometimes talking about these things like sexual obsessions can help you conquer them. I had terrible thoughts for many, many years, but once I got up the courage to tell my T about them, about how they made me feel, I was able to gain some control over them. I have been doing meditation for several months so when the thoughts would come up I would go into my meditation phrases and manage to put the obsessions out of my mind. I do take Xanax for anxiety but that is all.
