==First retraction of the foreskin==
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 sensitiveglossy 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 present.
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.
There is no particular reason to touch the head so, if it is sensitive painful to touch, then one may simply avoid touching it. Keeping the foreskin forward in its protective position over the glans penis also prevents pain.
