The frænulum is a normal part of the anatomy of the penis. It is virtually always there unless there is a congenital abnormality (hypospadias) or the penis has been mutilated - as in circumcision.
Therefore it does
tend to pull the glans down - if
you pull the foreskin back firmly. The question is - why
would the foreskin be pulled back firmly? More to the point, why would that have anything to do with normal sexual function or why would it even matter? Clearly, the only reason it would matter would be if it is uncomfortable.
And the only likely situation would be that in intercourse, there happens to be too much friction
dragging it back, which clearly indicates a severe lack of lubrication
, possibly made more noticeable by substantial vaginal tightness which is otherwise, entirely desirable. So while it is
entirely appropriate to undertake the stretching as we describe on this site, you also have to examine what is really
going wrong with sexual technique resulting in the woman not lubricating (or simply use an "artificial" lubricant, particularly if a condom is used as it in many or most cases, should be!
