That is still another level than actual shit though. No one argues mouths are hygenic. But to compare it to your butthole, I mean, no. There is a reason stuff like handwashing or flushable toilets increased life expectancy quite a bit, people stopped getting sick from all the stuff that comes out of our shit.
Any house with a toilet is covered in a micro layer of shit particles so most likely.
Do you press your mouth against the toilet and flap your tongue around on it?
Is your ass always covered in shit? Maybe wash more dude.
Again people do that to each other’s mouths which have way more bacteria and decaying food in it.
