I'm 14 years old and down by the beginning of my penis, there is a large red bump, about the size of maybe an air soft pellet, maybe smaller, and its came out of nowhere and it is starting to hurt, only when I move around though. I have had no sexual interaction EVER and I really would like to know what this is and why it is hurting. I do believe it has a pinch of white in it, and I'm now extremely worried. What could this be, and what can I do???
