Mortarana,
Perhaps I wasn't clear. That most sexually active women are on the pill is just a reality, but a reality which means there is less incentive to use condoms since pregnancy is no longer an issue. As a result, the chance that a couple will risk unprotected sex is higher than it would be if a screaming baby might come of it.
But even the prospect of a screaming baby didn't stop young people having sex int he heat of the moment, did it. So at least circumcision will mean he has a reduced chance of getting an STD.
I will tell my son he must always use a condom to protect himself from STD's. I will tell him that circumcision gives only a small amount of protection and he will still have 80% of the risk an uncircumcised guy has whereas a condom, used correctly, gives almost complete protection.
And I will know that, should passion result in unprotected sex, at least he has a reduced chance of catching a disease.
Of course, on a national scale this would mean only 80 cases of STD's would present against 100 that present with uncircumcised men.
Enough to recommend universal circumcision? No. But certainly a benefit of circumcision to add to the other benefits of circumcision.
