Invent one with that sprays soapy water and I'll get one. Until then I'll continue using the shower head and/or clogging up my pipes with "flushable" wipes.
Wiping your ass with nothing but toilet paper or plain water is unsanitary and weird. It's like washing your hands without soap.
It's not like you're eating out of your ass. There's actually a reason why you must wash your hands with soap every time you have had your hand in the nether region.
It was actually worse than that .... a communal towel that was given a quick rinse with water, quick dry and handed back into circulation in the communal toilet where you all sat in one room staring at each other.
