The foreskin is a normal anatomical feature found in all mammals. It has evolved to protect the penis, and contains unique structures. The foreskin is the most densely nerve laden part of the penis, containing 240 feet of nerves and 20,000 nerve endings. The foreskin contains dense concentrations of Meissner’s corpuscles, which are special nerve endings especially sensitive to light touch. These highly specialized nerve sensors enhance sex in the adult, and are one reason why genital cutting is so painful to an infant. As a protective cover, the foreskin acts in the same way the eyelid functions. It keeps a sensitive area protected, but retracts as necessary. We shouldn’t assume the foreskin is an unnecessary “flap of skin.” Nature’s design doesn’t make mistakes.
