What do I do if I get really aroused during an exposure

today's exposure exercise. I look at the face of a person I have sexual thoughts about and I feel that as soon as I can connect that face with sex I am attracted to it, and I feel like I can touch my self on sexual way while looking at that face, and I can imagine it and get it as an urge..it seems like I am stopping myself because it is horrible, not that I don't want to... I get stuck a lot with this and I don't know how to get out...I can't...

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 try not to pay attention to my thoughts. I realized that when a thought pops up for me (sex scene), I go back to it a couple of times to figure out what I am I also felt whether, and I simply decided to let them go..however, I am worried about that feeling of sensation in my groin at those scenes in my head, I am afraid of the fact that I can feel something while I am imagining it and that it is spinning non-stop in my mind! l imagine Just A part and it's constant for some days (like a part of a face, a look or something) the whole scene goes to that I spontaneously imagine and I have the feeling that only that part "turns me on" at the beginning, then the rest... Have you had similar experiences and how to overcome? thank you (edited)
