The Skin on Your Butt

Think for a moment about the skin on your butt.  If you live a normal urban life, the skin on your butt only ever touches fabric (underwear, pants, bedsheets), water (shower, bath), toilet seat, toilet paper, and the skin (and maybe lips) of another person.  Fabric, water, toilet seats, TP, and flesh.  That's IT.  That's all your butt ever gets to experience.  Isn't that kind of sad?
