I'm not familiar with all the subtypes of OCD and apologize if you already know this, but have you read about Harm OCD? I think there's also a subtype in which people do not have compulsions, but again, I'm not educated in the subject.

I have severe OCD and was just hospitalized for it because I was not medicated properly. OCD can be cruel. Having unwanted intrusive thoughts that won't go away or are very hard to make go away is OCD normally. That's what I was told by my therapist. I have it very badly and now that I'm on new medication, I'm able to deal with it, but I had a lot of harm OCD thoughts and eventually led to actions. I'm very thankful I'm alive now that I can think clearly, but it is a very scary place to be.

I've gone up and down through all levels of severity of ocd my whole life and in my non-professional but lived experience opinion, it just sounds like regular intrusive thoughts. Obviously, more severe than the average person has, but I've seen many people with autism also say they have these similar ocd-like traits. Repetitiveness and intrusive thoughts are integral parts of how both of our brains are hardwired, however if you don't really engage or feel anxious about it then I don't think that qualifies as the actual disorder.
