Removal of the [[foreskin]] permanently exposes the [[glans penis]], tightens the residual [[shaft skin]] and reduces or eliminates gliding action. It also results in [[keratinization]] or callousing of the [[glans penis]] because of chafing and abrasion from clothing, leading to loss of sensation. Removal of the [[foreskin]] can lead to [[trauma]] of the [[penis]] (friction irritation) during [[masturbation]] due to the loss of the gliding action of the foreskin and greater friction, requiring the need of [[Masturbation#Lubrication| artificial lubrication]]. During sex, the loss of gliding action is also thought to cause pain, dryness, and trauma in the [[vagina]] of the female partner.<ref name="warren-bigelow"/> The [[trauma]] and abrasions of the vagina can lead to easier entry of [[Circumcision and STDs| sexually transmitted diseases]].<ref name="Bullough2014">{{REFbook
