There is much controversy regarding [[urination]] with a retractable [[foreskin]]. Either retraction of the foreskin or non-retraction of the foreskin is possible. Some believe that it is harmful in some way to have [[urine]] in the [[foreskin]]. There is no scientific basis for this view. The foreskin developed over about 1 million years of evolution based on survival of the fittest. If the foreskin made men less fit to survive, the principal of natural selection would have eliminated the foreskin, but it did not do so. The [[preputial sac]] of the foreskin is covered with mucosa, not skin, so it well tolerates the moisture provided by [[urine]]. Some men with a '''long foreskin''' report that it is awkward to retract the foreskin for urination, because the '''long foreskin''' is constantly pushing forward to return to its normal position, so they do not retract their '''long foreskin''' when urinating.
