Biting nails and cuticles or tearing them off to maximum extent - often until they start bleeding, biting interior cheeks and exterior lips, sometimes biting horny skin areas on hands. It is there all time - I do not take notice of it anymore, unless I get reminded by someone of fellow man. It is quite embarrassing, especially in public. I can not stop and am literally used to plunging my teeth into the nailbeds.
Also often touching and scratching facial parts.
Well, I have been doing so all time. I can not stop anymore.

I think you do it to a greater extent than I do... I do especially the face touching (nose, lips, ears, eyes, eyebrows, cheeks).
I do the hair pulling / plucking thing especially at my ears and the inside of my nose (too much hair grows there to my annoyance) and sometimes at my fingers. When I pluck hair from my nose it seems I pick my nose which I also like to do... Biting my nails and the skin on my fingertips is common to me.
