I'm 14 and have only had sex once but this started before then. It seems like these little seeds are everywhere big and small all around my testicles and halfway up my scrotum. I never really Paid any attention but they have been like this for a year or two and some are in groups others not. When I squeeze them nothing happens and I don't have any irritation. But there is this one bump that is like black under the skin with like a little tiny black hole coming out of the skin. It's worrying me now because I think it might be gangrene. I masturbate every other day and sometimes stop for a week or so. Whn it first started I restrained from it for month Or two.
