if the africans would just use a condom....
we wouldnt have to worry about cutting off bits of genitalia.
PRECISELY!
If we even consider the studies valid, ircumcision does not protect fully against HIV. The recent studies convey the idea that cut=protected, but that's simply not true. By FAR the best protection is using a condom, which is cheaper and less dangerous than circumcision. So proposing circumcision when condoms are so superior an option is bad medicine, and very poor logic.
It holds moisture in? Great. That certainly has been a problem for my circumcised cock.
It serves as a protective layer? Is that so important when you wear clothes?
Better sexual pleasure? Really? Is that quantifiable? (The more cells theory, probably.) I'd bet that most circumcised/uncircumcised men like the way their cocks perform and I bet women feel the same. That's just my guess, though. You're the expert.
No, the foreskin doesn't just HOLD IN moisture, it generates it, providing lubrication for sex and removing the entire burden from the female. This is obviously an evolutionary benefit as well.
Protection is very significant. Clothes do NOT protect in the manner I'm referring to. In fact clothes are very rough and thus the circumcised penis becomes cornified (toughened tissue) and loses significant sensitivity. It's similar to how very calloused finger tips are less sensitive. The foreskin is smooth and moist, and maintains a smooth, highly sensitive, and moistened glans. Nothing else can provide this function.
More sexual pleasure is another thing that is simply fact. Far more nerve endings, the intact frenulum which is the most sensitive part of the penis for most men, the more sensitive glans because the skin is not cornified, the lack of scarring = more sensitive, and also, the foreskin provides additional friction during sex. Furthermore, most men who have been circumcised as adults notice a loss of sensitivity, although it does not compare to what men circumcised at birth experience -- they lose MUCH more sensitivity (for reasons I can go into if you like).
