The female ejaculation exists and there is no doubt but occurs in a small minority and that most women there is no expulsion of liquid orgasm.
Ejaculation occurs at orgasm and is ejected as a powerful jet through the urethral opening. There was a time when people used to think that women could not ejaculate like men therefore are attributed to excessive ejaculation vaginal secretions and in some cases, lack of retention of urine.

Whence comes the woman's ejaculation

It is known that female ejaculation does not come from inside the vagina but from the urethra, the same hole where urine flows, emerging as a jet and abundantly many women believe having urinated.

Ejaculation in women occurs at orgasm, just as in man and the liquid is expelled from white to transparent and certainly does not smell like urine, so it is easy to check the differences.

From where the female ejaculation

The liquid that emerges in the ejaculation of women comes from the Skene's glands, similar to the prostate in men; these glands are found in the urethral sponge, which swells during arousal due to abundant blood flow it receives.
In that zone is located the female G-spot stimulation which may lead to receive ejaculations similar to those of men.

For some women ejaculate and some do not

Female ejaculation is possible depends on the size and opening of Skene's glands in some women are small and sometimes not there, this is because very few women can have ejaculations.

To check if you have ejaculation during orgasm is necessary to find and stimulate the female G-spot, although some women say they can ejaculate without any special stimulus.
