I am fifteen and I was doing kickboxing the other day and was kneed in the penis. I was flaccid at the time and it Hurt a lot. I need not hear a pop or crack as it was too loud in the gym. I cannot get an erection and there is a small bump in the side of my penis. I don’t want to tell my parents and I don’t know what to do. Can someone please give me advice. I’m very worried.
