DescriptionA non-retracted and retracted foreskin, male age 29.jpg
English: In the left image male's (age 29) foreskin has only partly retracted off the glans penis even if male's penis is fully erect. In the right image the foreskin has been manually retracted off the glans penis by hand. Usually the foreskin retracts automatically during erection process. This subject's foreskin doesn't always retract automatically beause it is long and thight enough to stay on the glans penis in spite of erection.
