am i weird or ocd?

Now I wash my hands BEFORE i go to the bathroom in a public restroom. I will do it again after, and then also deposit used papertowels behind the door as i don't like touching the knob. I know 90% of that sounds, well, sanitary. But the washing before, isn't that just good protocol? You'd think your hands were dirtier before, and your neighbors downstairs would remain clean. Unless one is not taken to being clean of course, but that wouldn't make me out of the ordinary would it?
