Ejaculating over exposures

I might need an expert to help me with my OCD exposure and response therapy. I am doing exposures to sexual material that triggers my OCD. Stuff that many here would consider mild is enough to make me shake uncontrollably from the anxiety that it gives me. I could do nofap when I was suppressing it with other compulsions, but I do not want to do that any more. Sometimes it makes me ejaculate in my underwear when I do it. I am not touching myself and get not enjoyment from it. It is working as I am becoming less reactive. It is just so difficult. Maybe I am pushing myself to hard or maybe I am not trying hard enough. Maybe I should step it down. Never use fap as a was of suppressing anxiety or fear. This is where it gets you. You can come to relate anything sexual with your triggers.
