Anyone with contamination OCD without fear of germs, illness or other?

Hi! I'm in the process of getting diagnosed for my contamination OCD, but I can't exactly pinpoint a logical trigger. There's lots of things that feel "dirty," and a lot of those things do have legitimate roots, but I don't really care about getting sick, or germs or other things specifically that I know of.

Does anyone else experience the fear/anxiety around contamination, but about nothing in particular? I'm trying to figure out if I have a deep-seated fear of something specific or if Contamination OCD can exist without a particular subtheme if that makes sense.
