the thought was really scary why am i not freaking out???

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

so i start therapy tomorrow. but bro it’s just getting worse and im so scared. like the thoughts are getting more frequent and i genuinely feel evil and i hate it. i keep thinking what if i do it and im scared im eventually gonna. i’m scared i give off a creepy vibe or im lying to myself or others. please tell me is this ocd? do i need to be actually worried? i’m really freaking out

does anyone has any tips how to stop the "what if cycle"?? i have very disturbing what if thoughts on daily basis and they're rlly scary always. i know they're not real but sometimes they feel so real and possible to happen and i hate this
