Gonna gross the wives and girlfriends out right here, right now. Sorry.
Everytime a guy walks into a public restroom, he is probably transferring thousands of germs from the door knobs and handles....right to his male unit. Not kidding.
--Touch knob, unzip drawers, hold unit. Yes, it depends on which hands he uses for both, but the chances are high. I've recently started to wash BEFORE handling the goods, in public restrooms.
The downer is that it doesn't matter how much of a great hand washer he is when leaving the restroom....he's bringing 300 people home to you!!!!!
