this is not a good poll. EVERY guy has\does pee in the shower.
the question is, have you ever tropped a cleveland steamer in the shower. like - for example, if you had a sudden bowel movement and thought you were about to expell a gastrious cloud, but instead a large nugget of feces dropped in between your feet.
THAT should be the question.
//edit
one time i was secksing this womanz in the shower, and she was finishing me off with an oral exam, and as climax was attained she pulled her face away from the member to let it fly upon her bresteses, and the member saw fit to make romance explosion on her face, along with one or two shots over her head.
that was funny.
