Intrusive dreams + groinals + lack of anxious feelings = 😭😭😭

Every time I go to bed late and I’m falling asleep, I suddenly get an intrusive thought of a child’s face and my groinal area always responds to it. It’s such an uncomfortable experience. I am way too tired to try and freak out so I end up falling asleep. The next morning I’m always trying to figure out whether I had the groinal response first or after the thought. I start giving OCD power but it feels like If I let it go, then I’m in denial or whatever. I don’t want to ever do anything sexual with a child. I don’t even feel comfortable talking platonically with people who are 17, much less a child. My therapist says that I have a deep rooted fear that I’m this horrible person and that OCD loves to feed off of it. When you get a groinal response, it makes the thought that much more real. I never want these things to happen. I want to only be into adults. It’s so discomforting and stressful. Especially since I’m hyper checking how anxious I am, and if I find I didn’t really have much anxiety, then I’m like “well if I didn’t have anxiety, what does this mean?” And more questions occur til I end up in a rabbit hole

I’m on my period and o think my ocd feels a little worse today… I feel anxious and like something bad is about to happen, like I can’t move or talk cause I’ll freak out or snap and do something. Also I had a gronial response about an SA topic and I feel horrible, I’ve noticed that I do have these gronials as if I’m actually into that but idk if it can happen that you have the gronial and think “oh I’m horny, not about this but I am” is that possible? Idk how to say it… also I think I just want reassurance but I’m also scared…

So I was enjoying some “me time” and had intrusive thoughts, but it felt like just for a second I liked it. Like I’m holding myself back from “enjoying” the thought. And the thoughts are related to things I was into when I was younger, but sometimes I feel like I might still like it even though 9/10 I wouldn’t give it a second thought. Is this common? Or is this just denial? Thanks
