Female ejaculation (also known colloquially as gushing or squirting, although these are different phenomena) refers to the expulsion of fluid by human females from the paraurethral ducts through and around the urethra during or before an orgasm. The exact source and nature of the fluid continues to be a topic of debate among medical professionals and is related to doubts over the existence of the G-spot.
In questionnaire surveys, 35–50% of women report that they have at some time experienced the gushing of fluid during orgasm. Other studies find anywhere from 10–69%, depending on the definitions and methods used.
The G-spot is an area 1 to 1.5 inches across and located about two finger joints deep into the vaginal entrance. Its sensitivity to stimulation was first discovered by Ernest Graefenberg (1881-1957 - the G-spot is named after him) in 1950. As a result of direct stimulation the spot, which works like a sponge, will fill itself with fluid. To date it's unknown specifically what these fluids are, from where exactly they originate or what their exact function is. However, they're neither urine nor vaginal fluids and have no lubricating effect. A G-spot orgasm, combined with ejaculation, is much like the male orgasm, including the physical fatigue and the need for a refractory period. The ejaculate will come out in different flows - different women have different numbers of flows and the amount of ejaculate is very individually determined. Science has different opinions on the question if all women have a G-spot and if all are able to ejaculate.
Stimulating the G-spot to the level where it will ejaculate requires three major items: time, tender play and (usually, but certainly not always) vaginal fisting. What you do is this: you start with stimulating the G-spot (which to some women is even more exciting than stimulating the clitoris) with your fingers and slowly and tenderly work your way to the point where you can slip your hand into the vagina (wear latex gloves at all times, not only to protect yourself but also to protect the tender inner vaginal tissue, and use lots and lots of lubricant). A good tip when you're using lubricant in and around the vagina is to warm it slightly before applying it. It's cold as it comes straight out of the dispenser, which to most women is very uncomfortable on the warm, tender and highly stimulated vagina. Simply have the dispenser ready, but floating in a bowl of warm water so it will warm up while you're playing.
