Actually, yes - you do grow new skin. You can easily see that on my penis. And the nerve endings never stop working, and you don't lose them, they just become less sensitive because the skin on your glans becomes thicker. When you restore your foreskin, the skin slowly goes back to it's original thickness, they become more sensitive.
