I did a quick Google to find out more about some of the HIV studies that you've alluded to (and before you have a go at me, I'll do more research later on today and tomorrow).
Yeah... there's a lot out there.
Quick synopsis...
Bad methodology accounts for most studies showing no effect and ALL studies showing the opposite effect.
For example... one study you cite posits that Circumsized virgin males have a higher rate of HIV infection than uncircumsized male virgins. As if that has any relevance to the question, because, clearly, circumcised virgins with HIV DID NOT CONTRACT IT VIA SEX.
Many african tribes perform the ritual in extremely un-sterile conditions. This accounts for those infections and has no bearing on the actual study of sexual transmission rates.
Another source of error in many studies is the reliance on laboratory testing rather than actual epidemiological studies. ( the same kind of studies that clearly implicate the cultural practice of multiple mistresses as being a huge factor in heterosexual transmission rates.)
Solid methodology that properly accounts for these kinds of erroneous data is actually quite clear and is fully backed up by similar studies of HIV transmission in Israel and HIV transmission among heterosexuals in the West.
The higher the prevalence of circumcision in a population, the lower the rate of transmission among heterosexuals.
Circumcision status is a very strong predictor of HIV risk.
The science has been independently verified by WHO.
Really. Honest and for true.
But, y'know, even if Circumcision had NO benefit for lower risk of transmission...
even If I
hadn't been cut as a baby...
...the way some of you foreskin fanatics go on about your precious penis part...
... I would absolutely get cut ...
Just to distance myself from this ridiculous cult of the holier than thou penis skin.
