Always. It's amazing how many people don't. I've got friends who I've seen walk out of the bathroom without washing their hands. I can't even shake their hands after finding this out.
I am obsessed with washing my hands. I wash them like 4-5 times per hour, sometimes for no obvious reason other than feeling dirty.
I wash my hands before I go to the bathroom, Also public bathrooms are NOT cleaner than my dishes. It does sound like a lot of germ-o-phobes out here, must be a Ferrari thing.
I wash my hands before touching my dick, then I pee and flush using my shoe, then I take a napkin I always carry some in my pocket, to open the faucet and wash my hands always using the napkins to touch everything, then with a clean napkin I open the door and let the napkin fall on the floor. To open any doors I use the my knuckles.
