must be really interesting and funny for a german to read it hehehe.... but I think its quite normal to have a shower naked-even in puplic showers, I mean you have to clean yourself or not. In Japan before you go to one of the hot springs it is the same! But you sit on a little plastic chair and scrub yourself clean hehehe..for me it looked like some kind of ritual.
by the toilet thing- i have got a modern one.its different ;-) 
Richtig! you have to read it...Dobson wrote it in an amusing way!
In Japan people even have to jump in and big tube and naked together, men and women! Hui! If you go to Indonesia, we are also naked when shower in public place...but at least each space will be covered with plastic curtain or even permanent door! No other boobies are free too watch! hehe...
Cu you Thursday!
