Hello, a few days ago (like 2) I noticed a rather big bump on the side of my penis, worried of what it might be I went online and did some research. I figured it was a pimple after some research and continued with my day. Fast forward to today, the bump has not gotten larger nor smaller, but at this point it looked like a pimple ready to pop, however I did not. I then got in the shower and was washing my body, after washing my private area I realized it had popped. After looking at it, there was a hole, and a little white thing inside of the hole. I panicked. I am too worried and embarrassed as to what it might be to ask my mom (I am 15 and has never had sex) what might this be? Should I be worried?
