I am 14 and I have never had sex, but I have a small bump that looks like a pimple on the shaft of my penis. I squeezed it and white puss came out and a small amount of blood came out, like in a normal pimple. I am embarrassed to talk to my parents about it. If you have any suggestions please tell me.

Most likely ingrown hair, could be a skin infection, issue with heat or rubbing underwear.
Could be a dozen other things. So talk to dad, you will have dozens of bumps, rashes and issues over next 4 or 5 years
