Does an otherwise clean penis have meaningfully more bacteria on it than other parts of the body? I suspect that when I touch my oenks I'm transferring more bacteria onto it from my hands than vice versa, considering my donger mostly stays in my pants while my hands manipulate objects all day long.

It's the sweat production. Imagine someone sticking their hand in their armpit, then shaking your hand.

Vs putting a hand on their bare hip, then shaking your hand.

Also, groin sweat smells different and probably has extra hormones/pheromones in it

I imagine that every time I shake hands with someone.

Maybe that didn't just remove their KFC-greased, butthole-stinky finger from their nose before we shook hands, or maybe they did.

Yes it does. Dark, dank places grow much more bacteria than other places. It also happens to be right near your poop hole.

It isn't that hard to make an agar plate and put it under a lamp for a few days. Why you try a swab of crotch juice and a swab of face juice and incubate them each and see what you get?
