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

I need advice for intrusive thoughts. I used to feel like I could handle them. They weren’t nearly as bad as the things that related to my actual life. But now, I’m suffering. I haven’t had a sexual experience in over a year that didn’t involve constant intrusive thoughts. Most are somehow related to kids and I keep chasing off the thoughts but it’s so bad. I know you’re supposed to ignore them but I don’t know how I can just ignore that and continue what I’m doing. But they’re coming on stronger. I had one earlier I could not get rid of just as things finished so the thought came on strongly just before my orgasm hit and now I feel absolutely disgusting. I hated the thought and I know it’s not me and it was not enjoyable but it still feels like I was getting off to it. I feel sick. I’m so fucking tired of these thoughts. They’re in my every day life too and it’s all the time. I just want it to stop but ignoring it feels so wrong. What should I do?

Today has been really hard I feel like I can’t even breathe I feel like a pedo for real :( whenever i think during my alone time i try and coexist with it? but when i decided to think and think i panic and panic more and more i start feel more guilty guys I can’t take this anymore bc when I kinda feel certain it fades aways i think logically i know i probably am ok :( but it’s so scary for me what if i did actually act on the thought and I didn’t realize? And now reflecting it ???

I’m a csa survivor which made me develop hypersexuality while actually being a asexual individual. (Where I did CP and talked to groomers and sexted, ect ect) A few months ago I’ve started to heal, but the fact that I’ve seen so many private parts since I was idk, young? I imagine them everywhere, it’s really frustrating and sometimes I also get intrusive thoughts about other kids or my siblings. It’s deeply distributing but I also kind of think of it from a curious kind of aspect which I despise too. Honestly I have a hard time with any kid in underwear, my intrusive thoughts have been ALOT the last months and they’re really really overwhelming. I also easily go into overanalysing them or even trying to figure out more clearer the thoughts to “test myself”. I think, I hope. Idk it’s scary
