I feel arousal about my thoughts no one else does on here

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?

Just gonna vent, this never happened to me before during my 20 years alive. Whether it is POCD or not, I have truly lost my sense of self and my innocence. Why of all things did this have to happen. Ive been experiencing more strong groinal responses and mixed feelings of arousal regarding specific thoughts. Its so odd, cause last month none of this happened, it was mainly just anxiety and mental breakdowns. Never did I think I would experience physical sensations as well. Acting on compulsions as well left me feeling absolute confusion, Ive stopped doing that but now I get the urge here and there, and Ive learned to sit with the discomfort. All this leaves me with more questions on whether I will truly get through this or not, or if people will understand my situation. On certain days I feel fine, on other days its sheer terror. I blame myself mainly for this all, It is scary as these images, causing both arousal and terror, only result in me feeling like a shell of my former self

Hey guys recently I been facing anxiety because I have a fear that I acted on something I know I didn't do but it feels real because it felt like I had attraction and arousal to a younger photo of a ex gf I feel so weird feel so anxious I need help Idk what to do
