When a girl has been "holding it" and is approaching the point when she wets, does she wet because: -

A) The pain and discomfort of a bursting bladder is just too painful, so she 'lets go' and wets herself ?

OR

B) There is a 'containment failure' and she wets because she just can't stop herself from wetting, even though the pain/discomfort is still bearable ?

You'll have to hope some of the models respond to this one.

I have the same question and have often wondered. Please models, respond.

I've made similar inquiries at www.holdyourbladder.info, and my overview titled, "Bladder Capacity in the Practice of Water Holding" is available there.

Generally, the bladder's detrussor muscle goes through a process of overall stretching by contracting in spots, which are felt as surmountable urges, until a fully coordinated contraction overwhelms the sensing part of the organ, the bladder neck (B). That's the scenario everyone here is probably most in tune with, and you can have faith in its inexorability.

But many girls do have to release intentionally at high volumes, because there are various ways that the sphincters can gain a mechanical advantage (A), most commonly via collapse of the bladder neck, which is like folding the outlet shut instead of constricting it with the pelvic floor muscles. It's not necessarily just a matter of "letting go" at that point—she'll probably have to push with her abdominal muscles.
