New tests in the late 90's were able to determine exactly where female ejaculate is produced: the Skene's glands, which are located in a woman's urethra and are made of tissue similar in composition to a man's prostate gland. Chemical analysis of female ejaculate reveals the presence of high levels of prostatic acid phosphatase, a chemical secreted by the prostate gland and found in semen. This would seem to indicate that a woman's ejaculation is similar in composition to semen (only without the sperm, of course). The G-spot orgasm, combined with ejaculation, is much like the male orgasm, including the physical fatigue. The ejaculate will come out in different flows, and its amount is very individually determined. Stimulating the G-spot to the level where it will induce female ejaculation requires patience, tenderness and... technique. But it's easier than you think. Start with stimulating the vagina with two fingers and slowly work your way to the point where your partner will tell you that she feels a "pinch". That's the G-spot! Once you've got it, stimulate it by pressing on it at regular intervals, harder and harder, until you feel the vaginal muscles contracting.
