Female ejaculation (also known colloquially as squirting or gushing) refers to the expulsion of noticeable amounts of clear fluid by human females from the paraurethral ducts and/or urethra during orgasm. The exact source of the fluid is debated, although some researchers believe it originates from the Skene's gland.
For most of the last century, there was controversy over whether the effect existed at all, and in recent history there has been confusion between female ejaculation and urinary incontinence. However, scientific studies from the 1980s and later have demonstrated an effect that is unrelated to urine.
Female ejaculation is mostly accomplished by stimulation of the urethral sponge (or G-spot, named after Dr. Ernst Gräfenberg), an area on the front vaginal wall. More rarely, ejaculation can be accomplished through external stimulation of the clitoris alone, the internal tissue of the clitoris then contracting and stimulating the urethral tissue.
WOHOHO....

Two Female Sexual Response Fluids
The two types of female sexual response fluids (cum) are clinically termed as female prostate and vaginal ejaculation fluids. The one most commonly seen in our culture is vaginal ejaculate, which lubricates the vaginal walls and oozes out during sexual arousal. Called, leukorrhea, it contains vaginal secretions from walls of the vagina. It's the vagina's natural way of cleaning itself. It is slightly acidic to keep infections away.
This ejaculate comes from the Skenes glands (the glands that make up the g-spot) and bladder and is similar to prostate fluid in men. This is because the female g-spot is essentially the equivalent to the prostate in males.
Female prostate / bladder ejaculate is what we are referring to when describing female ejaculate fluid and is less commonly seen in large amounts. This is not because women are not capable; rather it is due to lack of understanding of women's sexual health issues in this culture.
