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=DaiSik |first=Kim |init=K |last2=Pang |first2=Myung-Geol |init2=MG |title=The effect of male circumcision on sexuality |journal=BJU Int |volume=99 |issue=3 |pages=619-622 |url=https://onlinelibrary.wiley.com/doi/full/10.1111/j.1464-410X.2006.06646.x |quote= |pubmedID=17155977 |pubmedCID= |DOI=10.1111/j.1464-410X.2006.06646.x |date=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. Use of lubrication is optional for intact males. The motion of the foreskin stimulates the nerves inside the foreskin.

[[Circumcision]] was introduced in English-speaking nations in Victorian times (19th century) to unforeskin the penis, tighten the skin to make it immovable, and make it impossible to masturbate. It failed to stop masturbation, but it made it harder to do and less enjoyable. Kim & Pang (2007) reported that masturbatory pleasure decreased in 48% of the respondents and increased in 8%, while difficulty increased in 63% but was easier in 37%. They concluded that there was a decrease in masturbatory pleasure after circumcision.<ref name="kimpang2007">{{REFjournal |last=DaiSik |first=Kim |init=K |last2=Pang |first2=Myung-Geol |init2=MG |title=The effect of male circumcision on sexuality |journal=BJU Int |volume=99 |issue=3 |pages=619-622 |url=https://onlinelibrary.wiley.com/doi/full/10.1111/j.1464-410X.2006.06646.x |quote= |pubmedID=17155977 |pubmedCID= |DOI=10.1111/j.1464-410X.2006.06646.x |date=2007-03 |accessdate=2020-02-18}}</ref> Podnar (2012) reported much greater difficulty in eliciting the penilo-cavernosus reflex in circumcised men as compared with intact men.<ref>{{REFjournal |last=Podnar |first=Simon |init=S |author-link= |etal=no |title=Clinical elicitation of the penilo-cavernosus reflex in circumcised men |trans-title= |language=English |journal=BJU Int |location= |date=2012-02 |volume=109 |issue=4 |pages=582-5 |url=https://bjui-journals.onlinelibrary.wiley.com/doi/full/10.1111/j.1464-410X.2011.10364.x |archived= |quote= |pubmedID=21883821 |pubmedCID= |DOI=10.1111/j.1464-410X.2011.10364.x |accessdate=2020-08-13}}</ref>
