There is no minimum age for masturbation. Young adolescents may experience dry orgasms until secretion of [[semen]] commences.

The movable, internally-lubricated, [[Ridged band| nerve-laden]] erogenous [[foreskin]] and its [[gliding action]] is an important aid to masturbation.<ref name="kimpang2007">{{KimDS PangMG 2007}}</ref> [[Intact]] males simply use their hand to glide the [[foreskin]] back and forth. It is ''not'' necessary to retract the [[foreskin]] while masturbating. If the foreskin is of adequate length, then the [[intact]] male will usually keep it forward for additional stimulation. Keeping the head covered by the [[foreskin]] also protects the sensitive [[mucosa]] covering the [[glans penis| head]]. The motion of the foreskin stimulates the nerves ([[Meissner's corpuscles]]) in the foreskin. Use of lubrication is optional for [[intact]] males.
