Hello I'm 22 years old and since the age of 15 I have had white flacks only under my scrotam sack of my pubic area. It has never itched, never developed a rash, I have never seen anything crawling around like crabs, there has never been any blotches in my pubic area, it has never spread to anypart of my body nor to anyone else. I'm still not sure what it is, but I know it can't be crabs based off of tge fact I have none of the symptons. What could it be though?
