Wait … that’s what condoms are for
How can circumcision prevent STDs? In at least three ways:
* When the foreskin is removed, the skin covering the head of the penis becomes tougher. That may protect against “microtears” during sex that can provide a point of entry for germs.
* The mucosal lining of the foreskin may allow germs to penetrate to underlying skin cells.
* After sex, the foreskin may prolong the time that tender skin is exposed to germs.
