Random incident but I slipped after getting out of the shower and accidentally jabbed my penis with the teeth side of a hair comb. It left 2 very small and seemingly minor bruises about the size of a pen tip which is probably just because all the force was concentrated in a very small area. Is there any risk of damage when such a fine tip hits the shaft or is it just a broken blood vessel or two? It didn't break the skin or anything and I'm not in pain but always worried about injuries in that area healing wrong or causing issues
