What is more sanitary in your opinion?
Some history if anyone bothers to read:
Europe:
Europeans didn't have toilet paper until recently. The Romans used a tersorium, a sponge mounted on a stick. The sponge could be dipped into a water channel running in front of the row of communal toilets in the latrine, and rinsed off in that channel after use. If there was no channel of running water, a bucket of salt water or vinegar water would be used, as Seneca described in his Letters of Lucillus [70,20].
If neither a tersorium nor water were available, the Greeks and Romans used πεσσοι or pessoi, small stones. The tradition started with the ancient Greeks that three stones should be enough to finish the job. This convention has been very long lived, with a hādīth attributed to Muhammad specifying three stones as the ideal number for anal cleaning. The pessoi were also used in an ancient board game in Greece. Aristophanes wrote a scene involving pessoi in Peace in the 5th century.
Japan:
Starting in ancient times, and continuing all the way to today for real traditionalists, a chūgi was a special wooden stick used for cleaning the anus after defecation.
Its name means "wooden skewer", coming from the kanji for skewer and tree. Chūgi seem to have been depicted in scroll paintings since the 12th century AD, and must have been in use for some time at that point.
They're narrow thin sticks of wood, maybe 200 mm long, approximately 10 to 20 mm wide and a few millimeters thick.
