The hard, desensitised callus skin formed on the glans because of the protective foreskin being removed might have an influence in preventing minor cuts during intercourse that might lower chances of picking up HIV and other STDs, but consider the fact that Sweden, where circumcision rates are practically nil, has a lower HIV prevalence rate than Pakistan, where practically all males are circumcised. Malaysia, another Islamic country with near-total male circumcision rates, has five times the HIV prevalence rate as Sweden.

The reason for the difference is that Swedish men use soap when the wash themselves off. You know and I know that you can kill darn near any germ with a little warm water and soap.
Correlation is not causation.
Do consider that Muslim cultures are cursed with at least three to four times the number of homosexuals (those engaging in male/male sex) that places like Sweden.
Sweden being Christian, does not allow polygamy. Islam does.
When one man has four wives, three men have no wife.
Why do you think America forced the LDS church to give up polygamy?
