While waiting for further answers, you might look at "When did people start using the earliest form of toilet paper?? Did people not wipe beforehand?" at https://www.reddit.com/r/AskHistorians/comments/83970s/when_did_people_start_using_the_earliest_form_of/dvgr1hh/ . /u/CptBuck mentions not wiping in modern times.

With some hesitation, I'll mention my sibling reply with my links to an older version of the AskHistorians FAQ -- but since they are not in the current version, I suspect that someone at some point considered them all to be inadequate. So I won't link to it (directly).

So, more emphatically than normally, I'll note that this is a starting point, not to discourage discussion. Further questions, information, and debate are welcome, especially with the FAQ removal.
