As a smaller endowed guy, I can't pull my dick through my zipper to take a piss. I have drop my pants and underwear down below my balls. It's frustrating and embarrassing doing this at a urinal, because it takes longer when you have to undress, and redress. But I don't like using a stall and others hearing me pee. I always feel like it's a give-a-way that I'm small and hiding in the stall.
it's especially embarrassing when traveling with family or friends at restroom breaks. I always try to go first or wait until others have gone so I don't embarrass myself.
