Wait till you folk discover a hand faucet or a bidet like we have over here. It will change your world and leave your butts cleaner.
In most parts of Asia, people use water, in combination with TP. Western hygiene standards seem to be lacking in this area.
For most its the unfamiliarity with the idea which prevents the rational thinking behind it
I like to live in reality and not a world of what-ifs. About 50% of my shits are immediately followed by a shower. As far as I (or anybody else so far) can tell, whether or not I followed the toilet paper up with a shower has absolutely zero impact.
Again I ask, exactly what issues have you had that stemmed from using toilet paper instead of a bidet?
