The movable, internally-lubricated, [[Ridged band| nerve-laden]] erogenous [[foreskin]] and its [[gliding action]] is an important aid to masturbation.<ref name="kimpang2007">{{REFjournal |last=Kim |first= |init=DS |author-link=Dai Sik Kim |last2=Pang |first2= |init2=MG |title=The effect of male circumcision on sexuality |journal=BJU Int |volume=99 |issue=3 |pages=619-622 |url=https://ahcaf.com/wp-content/uploads/2015/08/kimpangstudy.pdf |quote= |pubmedID=17155977 |pubmedCID= |DOI=10.1111/j.1464-410X.2006.06646.x |date=KimDS PangMG 2007-03 |accessdate=2020-02-18}}</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.
