What is the foreskin used for?

The foreskin is specifically designed, First to protect the Glans penis while it is developing, this development is still taking place after birth. then to protect the glans penis sensitivity and cleanliness during pre puberty. After it becomes loose and pliable and able to be retracted from the glans ( this may happen well before or during puberty) It exposes the pleasurable and sensitive surface of the glans to masturbation and sexual intercourse while more then 20,000 nerve endings in the foreskin itself add further to the sexual experience. The foreskin itself is built with an internal mucous membrane lining similar to the inside of the eyelids to aid in lubrication and smooth pleasurable movement for both male and female. It is an important part of the function of manhood.
