No, I would not be freaked out if someone else had an erection. I'm not sure about other guys, though.
No, some of the other players are most likely having the same issue as you are.
You need a "go to" image in your head the second you sense an awakening about to begin down there. It has to be the grossest thing you can think of and fixate on it. For an example mine is "roadkill." It works to keep things under control every time! Pick one that works for you or use that one if you want!
I agree with TheAlpha1550. I wouldn’t be freaked out if anybody in the locker room or shower got an erection or had one when getting undressed. It’s just not a big deal to me. Probably because it happened to me a couple times. Haha yeah, I get hard if the wind blows it seems. Soon as I start to drop trou, it starts to go up. It just happens. No rhyme or reason, just a boner.
Good Luck
