Physical sensations that occur with certain thoughts?

Does anyone imagine they are doing their harm thoughts during an action, making you feel like you acted on your thoughts? For example, someone gave me a hug and at the last second I imagined I was touching something I shouldn’t during the hug? I want to make it clear it’s something I have zero desire to do! But the problem is, I thought it on purpose and it makes me sick !! Obviously nothing happened but my mind is telling me that was me trying to do it. Even though it was physically impossible to do. Am I a monster or could this be OCD? I’m freaking out and don’t want to be here anymore. I feel like I’m the exception and that this isn’t OCD. I know I post about this stuff a lot but I’m struggling and don’t know 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?

So, yesterday while I was laying in bed, I was relaxing when suddenly I had an intrusive thought about someone, but the thing is that it brought me a sense of enjoyment or calmness for a few seconds before it went away. Once it did, it was only until hours later when I realized what had happened and I began to freak out because I'm reading everywhere that when someone experiences this type of thing, the anxiety happens shortly after the enjoyment or "false" enjoyment. Can OCD do this?
