Functions of the [[foreskin]] include protecting the glans penis from abrasion, [[keratinization]] and moistening it by with body oils and moisture to keep it moist, smooth, and glossy with full sensation.<ref name="fleiss-hodges-vanhowe1998">{{FleissP HodgesF VanHoweRS 1998}}</ref> The glans of the [[foreskinned]] [[penis]] under the foreskin normally is kept moist to wet with a mixture of moisture and skin oil by transudation. The foreskin will also collect [[pre-ejaculate ]] when it is presentsecreted. There may be a substantial accumulation of beneficial [[smegma]] that has been collecting there harmlessly since birth.

It is normal for the glans penis (head of the penis) to be very sensitive to touch when the [[foreskin ]] is retracted for the first time since birth.
