What is a long foreskin?
By examination of the word 'long' one would assume the question
is referring to a foreskin greater than average. Average foreskin
covers the glans of the penis completely when soft. When erect
average foreskin typically slides back and exposes some if not all
of the glans. If a man has 'long' foreskin, by description alone it
suggests that the foreskin is of a greater/longer amount than
average. Some men with longer foreskins can have an erection with
no exposure of the glans. In other cases the foreskin can be long
enough to cover the glans during erection with excess at the tip.
Typically the position of the foreskin is dependant upon the
elasticity and size of the frenum, which attatches the foreskin to
the underside of the glans. The more flexible and abundant the
frenum is, the more likely the foreskin is able to slide up and
down.
