I am a 15 year old male who has never had sex or has done anything sexual with another person. I masturbate everyday about 2-3 times though. I notices these very hard white skin colored balls on my shaft. They don’t have any hair coming out of them and they can be squeezed and a white string pus would come out. They never hurt unless squeezed on to let out the puss. I know it’s not any std or even Molluscum Contagiosum because they don’t look like it nor did I do anything to get them like sex, and yes I know they can spread from not sex in some cases. It doesn’t look like ppp because its not near the heas. Most likely a pimple?
