Squirting refers to the fluid that is released from the vulva during sex or after reaching an orgasm. It is often mistaken to be urine, however squirting is a combination of multiple fluids. Squirting is not a sign of orgasm but is a kind of an effect of pleasure which is not experienced by all vulva owners. Some of the misconceptions about squirting is that it has to be in large volumes. Squirting can be a release of small amount of fluid.
