Thanks dude, helped me out a lot
I am 17 and I to play hockey and have delt with this. There is nothing wierd about getting a boner in the shower or locker room. We are all boys and get unwanted erections. No one should care, its just a penis and I am sure all the other guys are worried about the same thing. Masterbation can help, so try it before practice or in a stall before showering. Also, take a cold shower and do math problems in your head, or talk to your coach if you fell to embarresed to take a shower, so mabye he could stand in the locker room to make sure no one says anything, which I dont no why they would though. hope this helps man
