So far i have yet to find a woman that doesn't "gush" through g-spot stimulation, some find an initial challenge at letting to when they feel the urge to please but once they get past that they can have many many cllmaxs, ejaculating almost continuously large ammounts. For a lot of women it's something they've never experienced or thought possible and it can often require quite a good amount of finger strength and endurance to keep going but i'm sure the number of women that can ejaculate given the right partner is quite high.
