→Erection functions: Revise text.
The human race evolved over perhaps 700 millenia. The foreskin evolved its physiological functions that improve fitness for survival during that time.<ref>{{URLwikipedia|Evolution|Evolution}}</ref>
=== Erection functions ===
When [[erection]] of the [[penis]] occurs, the penis also expands in size both circumference and length, so more skin is needed to cover it and allow painless erection. The foreskin unfolds to provide additional skin and permits [[intact]] men to enjoy painless erection, unlike many [[circumcised]] men who experience very tight, painful skin when [[erection]] occurs.
