a year a go i was diagnosed with staff infection from a zipper incitent. it seems to be reacurring frequently and now i have found tiny welts on the shaft of penis. they do not itch and are not painfull. but i do have the constant feeling of needing to make adjustments becouse i am being pinched. but i am not being pinched. does any one know what this could be...i have looked into herpes but the symtoms to not seem to match.
