I still don't use toilet paper. I used one when I had access to it(in a hotel). I knew toilet paper existed as once when I saw it in movies or read about it.
Can I inquire as to where you grew up? I've genuinely never heard of anyone using just their hand, but I suppose it makes sense for poorer parts of the world. (no offense intended whatsoever)
India. No offense taken. FWIW, I can afford toilet paper. I just don't use it as I am habituated to using my hand. In case you are wondering, I can guarantee that the number of people who use their hand to clean their bottoms is much more than the combined population of USA.
