Premature Ejaculation has much more to do with excitement than with mechanical details. I commented on it in this previous posting
just a little while back. The point is - even circumcised
men with the loss of sensation that
entails, are prone to PE.
So long as your girlfriend maintains
lubrication, "drag" of the foreskin stressing the frænulum should not be much of a problem, even if it is
short and then even if you were not
using a condom, which of course we do
advise you to use with the usual criteria. The condom does protect you from this drag, which is in fact the very same drag resulting from loss of lubrication, that is responsible for condom rupture.
There are more
effective means of applying tension to the frænulum. We believe what we illustrate is much
more effective than simply pulling the foreskin back, and people have in the past expressed the not unreasonable concern that pulling the foreskin back
might stretch and distort the meatus.
The effect you describe of the frænulum pulling the glans down when you apply firm pressure is only to be expected and demonstrates nothing other than that the glans is more easily
distorted when flaccid and that pulling the foreskin back firmly is not a "natural" manoeuvre. Clearly
whether this happens to an significant extent when erect
is by far the more important demonstration.
So you have made the case for stretching your frænulum but there really does not seem to be any urgency
to do so.
