I knew a person on the spectrum that would chew on their pubic hair and another one that would eat their pimples.
No, your not weird. Yes, it CAN be a autism symptom. HOWEVER, what really matters is you aknowledge that this isnt socailly acceptable.
As long as it doesnt hurt your, you dont bother anyone with it, and it doesnt bother you, i dont see any reason to stop.
We all have these "weird things" about ourselfs. I cut myself made artwork in my own blood before, which is pretty weird.
