How do you guys stop a cumpulsion when you have already done it a few times? Got somewhat of a clear answer but realize you doing cumpulsions and need to stop

I already wrote about this and you really helped me, but now I wondered?! During the erp, I look at a picture of that person with some grimaces that the brain sexualizes, otherwise I have incest ocd! The person is of my gender, I'm not gay otherwise. And then, based on those facial expressions, the brain creates sexual images in my head, which I often feel as sexual and mental arousel. It is enough to see the picture or hear the voice of that person! Based on the pictures it gives me the idea of ​​sexually touching myself on it and climaxing while watching. I feel an urge (I tried something like that a few times ago and now I'm afraid of it), and then the exercise is over, but I stay until I get the answer I want and the feelings that would calm me down, but that happens less and less... Have you had any experience, and is it a compulsion? how can I stay after exercise with that feeling of reality.. Thank you in advance❤️

I noticed I’m starting to fall into a trap of a bunch of little compulsions- some of which are these little knee jerk behaviors that my brain is catching as I do them. For example, a short stand up at my desk (like sitting up and moving slightly to see above my cubicle) to check my surroundings. I’m struggling to catch it before hand- anyone got any ideas to help combat that? I really want to get past sitting with this and stop that little compulsion but because it’s become a habit, I’m just not noticing it until I’ve already done it. #Help

How?
