I have heaps of these things all over my ballsac. I have discovered that it is possible to remove them by breaking the skin and squeezing them out like a pimple. I believe they are mostly fatty deposits for some reason at the base of hairs, but I ain’t no biologomist.
I haven’t tried it enough to find out whether they just come back or what, and it smarts like a motherfucker to squeeze them.
So, at your own peril, if you really really want to do it this way, sterilize a very thin, sharp needle for use to break the skin with, and apply some antiseptic to the entire area when you’re done to attempt to clean up and seal the mini-wounds.
Again, I am no doc, just my own experience. (No, I have not attempted to remove vast quantities of them, just one or two by happenstance)
