Discover Italian supremacy!

Guess what is that? It's a bidet, a thing that's there only in the toilets in Italy.
Guess what's for? Well, after you "go to the toilet" you can quietly wash your ass there, without any problem. It's quick and easy.

I'm curious about what you do in the same situation, not having a bidet. Do you have a shower? Or you don't clean at all?
Or what else?
