Taboo Thoughts During S*x

Last night I was self pleasuring. I didn’t set out to think about anything weird but as I was doing it some pocd thoughts were in my brain. I did not get off to them, but I could have. Idk why that is but it is. Idk what to do and idk why I am this way. Is there some science about the brain while aroused or is it possible that the more gross or taboo something is I can like it?? Idk, just want to know if anyone can relate.

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?

I see a lot of posts about mas**rba**on, or during the s€x that they appear. Before, I felt like an urge to do it, (masterba.) and I tested my thoughts like that, but then it seemed to me that I could actually have an orgasm on that and it scared me a lot... Has anyone had such an experience and do you know how it is possible?! Thank you
