Jared! That's the wrong answer! Jerking off in the boys' room ten minutes before class will get you quite a reputation! And that'll fly around the school faster than you can clean up the mess!
An erection is a normal part of growing up. Almost everyone knows what's down there, and most know how it works. All guys get hard from time to time, and there's nothing to be ashamed of!
In class you just worry about class, and if you get an erection, you continue with the exercises.
It's that simple!
