Hi. I'm a 16 year old boy. i have a problem and i am really scared about it. i have small balls, very small on the shaft of my penis. very few of them are white and the rest are like skin color. they are not painful but i am really scared and i am shying to go to my doctor and tell him about this problem. and one more question is it normal that semen smells bad because mine smells bad. thank you very much.
