tw for this i’m babysitting my baby brother and hes laying on my lap and keeps trying to put his hand near my crotch and it’s driving me mad

POCD I was holding my nephew, he's a newborn, and he was getting hungry so he started squirming around and grazed my chest (yes I was fully clothed). Of course, that caused anxious groinals.. It didn't feel bad in the moment just very very anxious feelings, and without thinking, I was holding his head still right there and I was moving it closer in that spot (at least felt that way) to make the feeling continue I guess. It felt like an urge because of the groinals. It was such an anxious all over my body feeling. I was so anxious and triggered by that feeling. It's like my groinals were so intense I automatically leaned into them? So I ended up having another groinal. After that I put the baby down and realized what had happened. Did I just hurt my nephew without consciously realizing it till after? Is this OCD?

I feel like I did something bad now because I went to put the blanket on my brother and my hand was close to his back I had a thought before like “it’s time to touch him” and I stood up and he was on a call but he was sleeping so now I’m like why did I stood up? Was it to take the iPad or what exactly? I feel like a child molester I don’t remember touching his area or butt because I didn’t but I had my hand near his back I asked my brother if I did anything he said no I asked if I did anything when I put the blanket over him he said he was sleeping so that doesn’t reassure me So I almost acted on it?

I feel like I m*lested my brother in his sleep because I was thinking if me touching his area disgusted me and I’m trying to remember if I got up and touched him but I don’t remember I was laying down I asked my brother if I did anything he said no but how would he know he was sleeping? It’s like what if I did something that I don’t remember?
