Changes

By the onset of puberty, most, but not all boys, have a retractable [[foreskin]]. Boys with a retractable foreskin should retract and wash their foreskin when they bathe. Excessive washing and use of soap, shampoo, and body wash on the [[mucosa]] inside the foreskin should be avoided because it dries the oils from the [[mucosa]]l tissue.<ref>{{REFjournal
