Squirting comes from the urethra and is a result of the Skene's Gland (so-called female prostate) producing fluid. The Grafenberg Spot (G-Spot) is actually the base of this gland. Because the fluid expels through the urethra, there's often an intense urge to pee during extreme arousal. Most girls hold it back, not realizing it is ejaculate. They later pass it during urination. This fluid is NOT urine. It is odorless, mostly colorless and has little or no taste.
Female ejaculation (squirting) is worked up in the spongy area around the female urethra, better known as the G-spot. It's located at the upper part of the vagina, just behind the entrance at the back of the pubic bone. A woman or girl may have trouble finding it because it is not an easy spot to locate by yourself, but your partner will almost immediately identify it because it actually feels like a little sponge. When stimulated, this little sponge will fill itself with fluid. It's impossible to urinate while having an orgasm (the urethra will temporarily close up) so whatever it is you're doing, it's not urinating.

First, is that the fluid produced by the Skene's gland is more viscous than that expelled during squirting. It is the lubricant produced during arousal that allows women to be wet. It is nature's astroglide. Second, and here is the one that no one can ever answer, is that the Skene's gland does not have storage capacity. It is not a sack like a bladder. Even if it were capable of producing the volume, which according to all but a few zealots in the medical community it is not, it would not be able to store and thereby expel it suddenly.
I am not a doctor so I deferred to the experts when I first experienced it and wanted to know more. Yep, turns out the girl pissed on me. If it is enjoayble then I wouldn't worry about it and just enjoy; but if this is a discussion of the facts then these are easily enough explored. You will find a fair number of sites trying to justify otherwise, but they can never answer those key questions. Who really cares....have fun!
