The foreskin, even a healthy one, can be naturally short (does not completely cover the glans), normal (covers the glans in a rest state and begins to uncover it in an erect state), abundant (covers the glans even in an erect state until it is brought down voluntarily or naturally during intercourse).
Consequently, a normal or abundant foreskin may be brought up to the fins; a scarce one up to the middle of the tuboid. The regressive effect of phimosis is achieved in both cases as long as the phimotic scar ring is made to rise up around the tuboid and not left down, out of the dilating action of Phimostop.
It is important to take care that the inner wall of the foreskin around the tuboid is also raised and not just the outer wall.
