fuck that noise. your penis is covered in skin like the rest of your body. you don't rush off to wash your hands every time you rest your head in your hand or scratch your elbow. unless you're holding someone else's dick in the bathroom, you're not going to pick up anything that isn't already in/on your body. people wash their hands in the bathroom for the following reasons: a) they're paranoid whackjobs like brad b) they're still brainwashed from their uptight parents/teachers telling them to wash their hands all the time c) they think someone is looking.

few people, even from group a) wash their hands at home. what strange thing is happening to your hands in a public bathroom that isn't happening in your own wc?

i also believe that a few germs here and there are good for people. even a lot of germs. don't wear shoes. get poison ivy. catch a cold. drink liquor. show your body who's boss. it'll keep you healthier in the long run if your body remembers how to fight shit off.
