Feeling gross

I have a fear of touching people inappropriately. When I was walking by someone, I intentionally thought a sexual thought, then I started wondering if it would make me move my hips, and then they moved a tiny bit. Obviously nothing happened. But I’m convinced that was me snapping. What I don’t understand is why the fuck I made a choice to think the thought. Usually I’m terrified of walking by people and try to pass them quickly. What could make me think the thought? I don’t even think the thought was about the person. I’m confused and scared

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…

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?
