Changes

Structurally, the penis is highly integrated. The [[glans]], [[foreskin ]] and [[shaft skin|skin of the penile shaft]] function as a single unit, not as a collection of separate parts with entirely different functions. The functions of the [[glans ]] and [[foreskin]] are similar, and overlapping, but come fully into their own at different times during intercourse.

The various parts of the [[penis]], including the [[foreskin]], form a functional whole. The foreskin is the primary sensory tissue of the [[penis]]. The [[ridged band]]of the foreskin is built to trigger orgasm and [[ejaculation]].
