“the glans, which is at the end of the penis, [is] covered with a very thin membrane, by reason of which it is of a most exquisite feeling. It is covered with a preputium or foreskin, which in some covers the top of the yard quite close, in others not so, and by its moving up and down in the act of copulation brings pleasure both to the man and the woman”
~Aristotle
(384 BCE– 322 BCE)
