do folkshave any information in how OCD ruminations can become physical sensation?

more advice for sexual/pocd sufferers I read somewhere that if you hyperfocus too much on your body's reactions to intrusive thoughts, you're unwillingly just making it intensify the sensations. Your body, after enduring severe anxiety and stress from sexual obsessions, will now just react to anything sexual that comes into your mind, whether forced or randomly. It can happen in any way. OCD makes anything possible, and is driven by fear. Knowing this I realized, it doesnt matter at this point, and to let it happen. And you guys should too. Remember what your real values and desires are. It can feel as real as it gets, but it is still not you.

Does it happen to you that when a person is specific in your ocd thoughts (my sister is my sister), that everything about her is a trigger for you when you see her? And the way he moves, talks, eyes, you suddenly sexualize everything, or is it just me? it really bothers me, because I constantly feel my groin, so I wonder if it's really OCD, or if it's something in me...

My OCD diagnosis is still very new, but now that I know what it is, it is clearly something I’ve had for as long as I can remember. Contamination/bugs and health have been a consistent theme since childhood, but religious/existential themes emerged during adolescence. Around that same time, there was also a good deal of trauma, and during middle school I started experiencing hallucinations. Tactile (like bugs crawling on me or biting me, an eyelash being stuck in my eye, but nothing was really there); visual (like moving shadows or things that would dart past in my periphery, and then I would just have intrusive thoughts of scary things around corners or under things); and auditory (an angry male voice that grumbles or yells indistinctly, or a high pitched noise like a microphone/speaker feedback but muffled and less sharp). Because of the religious denomination I grew up in, I initially assumed these were demons and tried to address it that way, but when I was 14 or 15, it occurred to me that those voices/sounds sounded like the way I felt, and the visual/tactile experiences happened during times of stress too — and so all of those experiences could just be seen as an expression of a fragmented part of myself. That acceptance didn’t make them go away — I still experience them now and I’m in my 30s — but it made those experiences less scary and more manageable. I also see now how these all pop up specifically when OCD obsessions are super triggered and when I’m super sleep deprived. Anyway! Since this diagnosis, and talking about the hallucinations at all, are new to me, I am wondering who else has had similar experiences. I don’t really know how much of the hallucination experience is OCD versus trauma, but it seems like this might all make sense under the “quasi-hallucination” label.
