The term "'''Gliding action'''" is used to describe the way the [[foreskin]] moves during [[sexual intercourse]]. <ref name="hill2007">{{REFjournal |last=Hill |first= |init=G |author-link=George Hill |title=The case against circumcision |journal=Journal of Men's Health and Gender |date=2007-09 |volume=4 |issue=3 |pages=318-23 |url=https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=04ace5046cc27f01b8fbe4aa359c059778983912 |quote= |format=PDF |accessdate=2023-10-02}}</ref> The [[foreskin ]] is internally lubricated with body fluid, so it glides frictionlessly over the shaft and [[Preputial mucosa| inner layer]] of foreskin. This mechanism was described by Lakshamanan & Prakash (1980), stating that "[t]he outer layer of the prepuce in common with the [[shaft skin|skin of the shaft ]] of the [[penis ]] glides freely in a to and fro fashion..."<ref>{{REFjournal

|quote=The outer layer of the prepuce in common with the [[shaft skin|skin of the shaft ]] of the penis glides freely in a to and fro fashion and has to be delicate and thin, as was observed in this study. [...] The inner lining of the projecting tubular part has the structure of the outer layer and adds to the thin gliding [[skin ]] when retracted.

==The normal, [[foreskinned]], intact penis==Several people have argued that the gliding movement of the [[intact]] [[foreskin ]] is important during [[sexual intercourse]]. [[John Warren| Warren]] & [[Jim Bigelow|Bigelow]] (1994) state that gliding action would help to reduce the effects of vaginal dryness and that restoration of the gliding action is an important advantage of [[foreskin restoration]].<ref name="warren-bigelow">{{REFjournal

|quote=During intercourse, the natural penis shaft actually glides within its own [[shaft skin ]] covering. This minimizes friction to the vaginal walls and opening, and to the [[shaft skin ]] itself, adding immeasurably to the comfort and pleasure of both parties.<br>Friction is not entirely eliminated during natural intercourse but it is largely eliminated. Friction can take place in the lower vagina, but only if the man uses a stroke that exceeds the (forward and backward) gliding range of the [[shaft skin|shaft's extra skin]]. And in such a case, there will be friction only to the extent that the shaft exceeded its extra [[skin]], which is uncommon since the natural penis has a propensity for short strokes. Primarily, it is the penis head that makes frictional contact with the vaginal walls, usually in the upper vagina where there is ample lubrication. [...] The gliding principle of natural intercourse is a two-way street—the vagina glides on the [[shaft skin ]] while the [[shaft skin ]] massages the penis shaft as it glides over it.

Taves (2002) reported that the presence and motion of the [[foreskin]] greatly reduces the force required for intromission of the [[penis ]] into the [[vagina]].<ref name="taves2002">{{REFjournal

==The circumcised penis==

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 of 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 |last=Bullough |first=Vern L. |init=VL |last2=Bullough; |first2=Bonnie Bullough |firstinit2=B |date=2014-01-14 |year=14 January 2014
