Groinal responses

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 keep getting these groinal responses when I think about kids or see one and it's really distressing, I only just learned that OCD can make you feel that and it's not actually attraction but it's so hard to remember that and I've seen people talking about accepting uncertainty but I'm so scared to think "maybe it's attraction maybe it's not" instead of "no it's not attraction that's disgusting" and idk what to do

Does anyone else when they have the thoughts, they feel against it, but they still get arousal or tenglings sensations in the groinal area? Because this is what I experienced today and I feel like crap. This is going to be very triggering for a lot of you, but there are a lot of times that I notice things from kids. For example, there is a thirteen year old kid who looks very developed for her age, and I take notice of (and this already sounds creepy to me) her chest. Today with my thoughts, I imagined as if I were touching it, and although I usually "no no or "I don't want to do that", she is a kid, etc., I still get responses in my groinal area, and It felt very real. Even now, I feel as though I am faking it, even though I groan 😮‍💨 from it, and feel as though I am a fraud. Does anyone relate?
