lol.. i suggest moving someplace with fewer medieval rejects.
what kind of stall are you guys talking about? im thinking like toilet stall.. but how in freaking crap would you get caught? i jerk off in bathrooms(highschool, colllege... malls.. resteraunts... work.. movies theaters... anywhere) all the damn time(i have to.. and its fun.. lol.. of course).. no one ever busted in the door and demanded to know what i was doing..

i think youre full of crap... or just a big uptight pussy.
if and when i go to a gym.. you can bet a million im gonna jerk off in the bathroom.

unless maybe theres no doors?
try a broom closet...
lol
