Toilet paper

This country definitely doesn't have a toilet paper culture.  The previous apartment where I lived, although it was kind of nice, inside its restroom, it didn't have the thing to hang the roll of toilet paper!  And now in my new apartment I notice that although it has the thing to hang the roll, they put it much too far behind!  So whenever I want to grab a piece of paper, I really have to twist my body backwards.

I wonder how do the local people clean their asses.  I just can't fathom it.  Yes, they use their bare hands and some water.  But my point is, right after they have wiped their asses with their hands and used some water in the process, their hands are still wet, but their pants are down.  So, how do they raise their pants without leaving wet marks on them?
