I wash my hands if I go poo, but I don’t usually wash my hands after I pee. If it’s a public bathroom, I think it’s much cleaner to go in, walk to a urinal, take it out, use it, put it away, and walk out, as opposed to dicking around touching the soap dispenser, the faucets, the paper towel dispenser, and generally lingering unnecessarily in the restroom.
If I’m at home the only difference is that I flush the toilet when I’m done. But really, there are much dirtier things in my house than my penis or the handle of the toilet. The keyboard I’m typing on right now, for example. And I don’t wash my hands after using a keyboard either. It’s healthy to come into contact with germs.
I wash my hands before I prepare food. I wash my hands after I sneeze on them. (More often when I feel a sneeze coming on I manage to get to a door and sneeze outside into some bushes or something.)
My sister has a habit of touching her feet all the time. Sometimes she will pick up her foot and hold her hand on the bottom of her shoe. That’s gross. And she has no problem eating after doing this. But she won’t eat food that has come out of a plastic bag that I have taken out and offered to her, because some of my skin cells might be on it.
