I can't imagine how could anyone go to WC and wipe his a** with dry paper. Thus you only remove the bigger remains of your sh**, the smell remains and probably some small particles. Its absolutely gross. Why don't you wash your a**es like in the arab world? Even in Burj al Arab - one of the most expensive hotels in the world in the toilets there are bidets! How could anyone walk around with his stinky a** in 21st century?
