Female ejaculation is characterized as an expulsion of fluid from or near the vagina during or before an orgasm. It is also known colloquially as squirting or gushing ,  although these are considered to be different phenomena in some research publications. There have been few studies on female ejaculation. Most of the research into the nature of the fluid focuses on determining whether it is or contains urine. The suggestion that women can expel fluid from their genital area as part of sexual arousal has been described by women's health writer Rebecca Chalker as "one of the most hotly debated questions in modern sexology ".

Squirting, orgasm, and female ejaculation: what’s the difference? - The Femedic
General consensus seems to be that squirting or gushing is the release of some fluid during or just before orgasm. However, not all women experience any sort of ejaculation of liquid at orgasm. Another study found that those who reported orgasming from inside the vagina ie, G-spot were more likely to report a spurt of fluid at the moment of orgasm. Similarly to the existence or non-existence of the G-spot , the chemical makeup of the liquid squirted, or female ejaculate which may or may not be something different , has long been the subject of debate. A firm conclusion about what it is and why it happens, and why it happens in some women and not others, has yet to be reached. But certain aspects of the debate do seem to have been decided by scientists, although not necessarily by women. A study looked at the chemical makeup of the liquid released when seven women squirted during sex.
The first time I saw squirting, I didn't really know what I was looking at. The squirter was named Cytherea, an adult actress who had become synonymous with an ability to ejaculate large volumes of fluid—that was supposedly not pee—during sex acts. So rare was this talent that a interview with Adult Video News described her as having a "one-of-a-kind sexual gift.
Woman A: I had been doing some research on squirting and one thing that came up a lot was to just let go and let your body do what it wanted while you were having an orgasm, so I tried it. At first, it felt like I had to pee and so I wanted to hold it. But when I just let go, I realized that I could squirt. Woman B: It happened a few months ago.
