Gliding action is the term used to describe the normal motion of the foreskin. This motion, pleasant and enjoyable according to some descriptions, can reduce friction during sexual intercourse. The existence of the gliding action is an important component of normal sexuality.

The fore/shaft-skin is attached to the penis only near the symphysis pubis and behind the glans penis. Anti-circumcision activists argue that the foreskin alternately everts and un-everts as it glides (rolls) back and forth. The gliding action was described by Lakshamanan & Prakash in 1980: [1]:

"The outer layer of the prepuce in common with the skin of the shaft of the penis glides freely in a to and fro fashion..."

Genital integrity advocates Warren & Bigelow claim that any gliding action would help to reduce vaginal dryness and that, in their opinion, restoration of the gliding action is an important advantage of foreskin restoration. [2] The protection of vaginal lubrication by the gliding action of the foreskin has been confirmed by a survey of women.[3]

O'Hara describes the gliding action:

"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 ski itself, adding immeasurably to the comfort and pleasure of both parties."

"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'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. (O'Hara, p.72)

Fleiss and Hodges claim:

The foreskin's double-layered sheath enables the penile shaft skin to glide back and forth over the penile shaft.(p.24)

The foreskin enables the penis to slip in and out of the vagina nonabrasively inside its own slick sheath of self-lubricating movable skin.(p.26)

Sexual effects. Taylor, a genital integrity activist, suggests that the gliding action, where it occurs, may stimulate the nerves of the ridged band [4], and speculates that the stretching of the frenulum by the rearward gliding action during penetration triggers ejaculation. [5]

Ease of penetration. The foreskin glides as the penis penetrates the vagina. Whiddon (1953) and Foley (1966) report that ease of penetration during coitus is provided by the foreskin.[6][7] In the first study of its kind, Taves tested the actual force required to penetrate. He reported, based upon a sample size of one, a ten-fold increase in force required in the absence of the foreskin.[8]

Schoeberlein (1966) reports that 8.8 percent of young German males aged 18-22 still have phimosis. This may prevent their enjoyment of gliding action.[9]

Alternate view

There is a body of opinion which holds that the foreskin is immovable, does not glide, does not have erogenous sensation, does not reduce friction during intercourse, and does not conserve vaginal lubrication; that circumcision prevents sexual malfunction.[10]

The presence of a gliding action is assumed by some, but has never been proven scientifically. Many people suggest instead that the foreskin is essentially immobile and does not glide. Claims of reduced friction or conservation of vaginal lubrication during intercourse are also doubted by many.
