Taboo Thoughts During S*x

Am I the only one who experiences this, or is it more common than I think? Sometimes, I find myself imagining what a couple’s sex life might look like, or what a person’s body might be like. I think it’s driven by curiosity, and I focus on it for a few seconds. When it comes to family members, teenagers, or anyone I feel uncomfortable imagining in this way, I used to be able to shake it off as an intrusive thought. But lately, I can’t seem to let go of it anymore. I’ve become used to the anxiety, but I’m stuck questioning what this means about me, especially since I’ve taken time to think about it. This is really stressing me out because I feel like a pervert. I’m hoping that this is something more common than I realize and that OCD is just distorting something. I feel like I really need some insight here. Any advice?

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?
