If I have OCD driven porn addiction will Exposure and Response Therapy help? I fear I cant control the urges and will just continue to relapse

I'm 17 years old I struggle with addiction I have a problem when I masterbate I have intrusive thoughts idk if I think them I'm so scared also back then I know when I was younger I looked at obscure things hentai all that my idk what to do even I feel like I'm a monster or im a bad person I need help I feel so distraught I feel like I can't live life to the fullest anymore even from last year I looked at content that was animated but it had a character in it that was underage I felt so ashamed and felt like a monster I had a compulsion to check it only to find out they are not around my age range idk what to do I probably sound like a freak I'm sorry I'm always trying to replay my memory and try to remember my intention and what I was doing how I come across how I was doing a action yk all that

I am doing ERP by my own because I can’t afford therapy. I exposed myself to babies photos online, changing diapers videos, baby genitalia . All was done with google . I honestly feel like I am predator by viewing these photos even though they are just babies. I seen also a picture on research article of a female patient she is a minor and they have done sexual abuse check on her . The image was so triggering, it was literally a vagina. ℹ developed lots if obsessions with increased groinal responses. And now I fear that I enjoyed all what I have seen.

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❤️
