Pictures Of Warts On Scrotum Bumps Appearing On Scrotum... Help?

Bumps appearing on scrotum... help? - pictures of warts on scrotum

Hello. In these days, I developed four shots in my scrotum, the size of a pea, white (but red when angry) without pain or pus / Drainage (but) easy to determine. I thought it could be an STD if they tested and said everything was negative. I spoke with two different doctors (one of the tests and a normal GP). We thought it was herpes, but test results proved otherwise, others thought they were just burnt hair (four at once?). I checked the pictures online and my shots are not as terrible as herpes and genital warts pictures, but still very visible and their relationship that nobody really knows what they are. PS I am 18 years, has sex with someone (even negative, and we had no sexual contact, because the bumps have appeared) and have never had problems before the skin (Psoriasis possible inherited from my mother?)

Please help me understand what is happening. Thank you.
