Hello , I'm 16 , virgin , I've had these hard white pimples in my testicular area and a few in the beginning of my penis. They don't hurt , it almost feels as there's a rock inside when you touch them. Some of them are softer. I've had them for over 3 years and now I'm starting to think about my future sex life and am a little concerned. If anyone could tell me what I'm dealing with here would be very nice. Thank you.
