When measuring length, only guys who are uncircumcised could boast that
their cocks are longer if, when erect, their foreskin still extended beyond the tip of the glans. Before my adult circumcision I remember that when I was really hard the foreskin no longer covered the very end of the head. I
think my cock looks bigger now (even though it isn't) because I have a very large glans that is always fully exposed. But as for the actual length
of a cut cock vs. an uncut cock, there really is no difference.
