Changes

The foreskin is in a transitional state during puberty and adolescence, in which it is changing from the non-retractile foreskin of childhood to the fully retractable foreskin of adulthood. Many adolescents complain of a non-retractable foreskin. Many teens need to do manual [[stretching]] to widen the tip of their foreskin if they wish it to retract. They usually achieve full retraction by age 16. The foreskin facilitates normal [[masturbation]].
