I can't help but laugh at the people in this thread.
I showered more than half the time after PE class, only exceptions were if I did not break a sweat at all.
I also showered after lacrosse practice and most games, unless I was too pissed to hang around.
It's not a big deal. It's honestly more unnerving to see some guys get so uptight/scared of it that they poison the atmosphere of the locker room.
Be comfortable with your bodies, bros.
Now see. I don't sweat. I can do an hour workout session and never sweat. I just don't have sweat glands because something given to me by my dad. That is why you have to shower more because heat gets trapped in my body more than a normal person. So if you want to see my penis that's on you I'm more concerned about my health.
