sure have. I'm not a doctor but anatomy and medicine in general fascinates me and from my research I can tell yall this:
True female ejaculation is supposed to be possible for all women but only a small percent of woman actually achieve it. The best way I can explain it is to think of a womans g spot as not a one particular small spot but rather a part of a larger gland (i'm wanting to say its an actual gland that's being stimulated) that extends into her body. The spongey texture that can be felt through the vaginal wall is the texture of the whole gland so when a woman gets aroused this "sponge" becomes inlarged with a fluid that under the right stimulation can be expelled through muscle contractions. That's why many women who squirt experience a building up of pressure before release. It's also why some women feel the need to pee when the g-spot is stimulated. Even if they have recently urinated. One thing I find repeated over and over again is that good hydration can actually help.
It's kinda interesting. if anyone wants to know more I can shoot you to some informative videos. just shoot me a message.
real quick as a side note... I can't squirt without both gspot and clit stimulation. Dont know if that's the case for other women though.
