These five photographs show the three zones of skin on a normal, intact (non-circumcised) adult penis:
B. the foreskin's outside fold (the area between the two lines in each photograph);
C. the foreskin's inside fold (the area below the lower [green] line in each photograph), visible only when the foreskin is retracted.
2. The foreskin retracted (manually) about an inch.
The area between the upper (blue) line and the lower (green) line is the foreskin's
mostly retracted outside fold.
The area below the lower line is the first half inch or so of the
foreskin's partially retracted inside fold.
3. The foreskin retracted. The area between the upper (blue) line and the
lower (green) line is the foreskin's retracted outside fold.
The area below the lower (green) line is the foreskin's retracted inside fold,
gathered behind the coronal sulcus.
4. The foreskin retracted farther. Almost the entire penile shaft is
now covered with foreskin. The area between the upper (blue) line and the lower
(green) line is the foreskin's retracted outside fold.
The area between the lower (green) line and the glans
is the foreskin's retracted inside fold. If the skin were released, it
would return to its position in #3.
5. The foreskin retracted as far as it will comfortably go. The area
between the lower (green) line (the only line now visible) and the glans is the
foreskin's fully retracted inside fold. (One of the fingers holding the
foreskin back is partially visible.) The entire penile shaft is now
covered with foreskin. Well over half of the shaft is covered with
the foreskin's retracted inside fold. Veins, arteries, capillaries, and
smooth glans texture clearly visible.
