The foreskin is the most sensory parts of the penis. In fact, it has more nerve endings than any other part of the penis. That makes it responsible for a tremendous amount of pleasure. The average male foreskin contains 20,000 nerve endings. According to one study, the least sensitive part of the foreskin is more sensitive than the rest of the penis. But the foreskin is much more than just a pleasure receptor, it has many function. Since the foreskin has the most number of sensory nerves, it serves numerous sexual functions. Since it acts as a cover to the glans of a penis, it also serves numerous protective functions. The foreskin is the most important source of an orgasm-inducing sensation. During intercourse, the foreskin produces a “gliding action” that reduces friction and enhances lubrication. On the downside, having a foreskin feels so good that uncut men are more likely to develop premature ejaculation. Some circumcised men have been able to regrown their foreskin with a device called a tugger. Any circumcised man can experience what it is like to have a foreskin by getting a mate with a long one to pull it over his helmet. This is called docking, cock docking. Foreskins can be used to make skin grafts for burn victims. One foreskin can actually provide four acres worth of grafted skin.
There’s an old joke about a rabbi who keeps all the foreskins from circumcisions he’s performed and makes them into a wallet. The rabbi’s friend remarks that it seems like he went through an awful lot of trouble just to make a wallet. “I know,” the rabbi replies, “but when you rub it, it turns into a suitcase.”
