Changes

Warren & Bigelow (1994) reported that the [[foreskin]] "provides slack [[shaft skin|skin on the shaft]] of the erect [[penis ]] allowing it to glide within its own sheath of [[skin]] during intercourse. This provides for more enjoyable intercourse for both partners and avoids problems with vaginal dryness." It follows that when the [[foreskin]] is amputated by [[circumcision]], the [[gliding action]] is not present, so vaginal abrasions and pain are more likely.<ref name="warren1994">{{REFjournal
