What should I do if I’m doing an exposure and i do a compulsion (even though I’m trying not to)? Does it ruin the whole exposure? Should I just keep going? Should I extend it?

If your mind purposely keeps fetching a repetitive word, and you’re afraid it will never go away, is the ERP therapy to STOP the mind from doing it? Or ALLOW the mind to do it, and not react? Also, is repeating a word in your head a mental compulsion? Or would that be the obsession? So then what’s the compulsion? Posting on here? Lol

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❤️

What would I do for ERP if my OCD says because I didn’t do something correctly or remember something I will have panic attacks that don’t end?
