I said 'on the body' for a reason.
Meaning the outermost layer of our body we know as skin.
And yes, your face has a greater variety of bacteria than the average pussy.
That depends if you're including facial pores, the nares, the lips (which bacterially communicate with the inner mouth), etc. If we examined a cm² of skin on the cheek (
facial) and a cm² of skin on/beside the labia majora, I really wonder whether the face would have that much more bacteria. Are you arguing for more unique species or for more cells?
Getting back to the original claim about circumcised penises being more hygienic, the burden of hygiene ultimately falls to the individual. I don't think any medical expert will disagree with you that uncircumcised men have to make a more conscious effort to remove smegma and other "crud" from around the glans of their penises, and this is what you need to watch out for because this is what's going to feed the bacteria and other microorganisms which can ultimately cause infections. But so long as the guy takes the time to scrub it off in the shower, I'd think he'd be fine.
Personally, I'm all for not circumcising newborns as well as making it an individual's right to choose as an adult (and not a day sooner) whether or not he wants to be circumcised. Unfortunately this flies in the face of many religions (which would argue that the state is oppressing their beliefs and customs) and parents-rights groups, so ... *shrug*. All I can say is, there are a lot of boys born to Abrahamic-religion parents who grow up to become adults that (1) don't share in that religious belief and (2) would not have chosen to cut off their foreskin if they could have made the decision today.
