Skin Colored Bump On Penis That Wont Pop Bumps On Penis?

Bumps on Penis? - skin colored bump on penis that wont pop

Hello, I'm 15 years old, a month ago, I noticed that these 2 parcels. Were white but have been especially skin color into the shaft of my penis in the middle. What are they? I have tried to see if he was a little, as usual, they are hard. Do not say you go to the doc, I went into the documentation (clompletly something else), but had some reason to see me there and saw my penis, and felt that everything was in order. There is nothing on the bumps Tho, I could see this area. What should I be worried

Note: I masturbate a lot, because of puberty, there is a role?
