I'm ace and I deal with sexual intrusive thoughts. The images and sensations feels so real I'm scared

Hey guys today I just wanted to come here and share an experience I have and I generally don't know what to do I feel like a terrible person for having these thoughts and for thinking them I genuinely don't know what to do I don't know the signs behind it and why I think the way I do but it's honestly driving me crazy I don't know what to do I have a pornography addiction for a long time it's where it's like anytime I'm an intimate moment or am masturbating my head just thinks these weird things always the same repetitive thoughts to of family members your younger sibling or a young child I myself am a 17 year old and I feel so disgusted I feel like I can't live my life anymore I feel like I'm a criminal cuz like it feels like I chose this these thoughts like I actively think them I don't know the signs behind it and I just really need professional help if there's any like therapist here that could fill me in that would be nice I would also like to know if you guys had any similar experiences because for me I feel like I have to rewatch pornography and do it right without the thoughts cuz I feel like the thoughts are just like to prevalent anytime I do anything related to masturbation why do I think this way I'm also just trying to be as honest as I can with this I'm not trying to make myself I guess a victim I'm trying to hold myself accountable if I actually am like this because I also have doubts in my head that tells me that I enjoy these things I feel like I'm going crazy someone help because it feels so real like I acted on them or that I was pleasuring myself to the thoughts and not towards the video it's just how can I live with myself you know also during it it felt like I was thinking the thought for a long period of time like it was dominating my head so I couldn't focus it felt l

Hi everyone I could really use some help on this topic. It’s hard to admit and talk about but after being on here I see that I’m not the only one! Still I would love some support and advice with how to deal with those unwanted sexual thoughts. For me it’s so uncomfortable and honestly gross when sexual thoughts get out of hand with normal people and also do extremely out of hand that even loved ones get involved. Like when I watch tv and all of a sudden I have these gross thoughts that I know if I accept they will go away but how can you accept something so gross? Would love some help!

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)
