Squirting is an English word that means "Squirt" but in the new trends of "sexual jargon" it has been called that to female ejaculation. The use of the term comes from the strong expulsions that a woman manages to perform involuntarily during an orgasm. The squirting is not the expulsion of a particular liquid, rather could try a combination of urine and vaginal discharge (liquid secreted by the gland Skene) that lubricates the vaginal cavity to facilitate entry of the penis upon voluntary coitus and conscious.
Now, beyond the scientific question that Squirting may imply, this is the subject of an erotic fashion in practice that has developed in the sexual and pornographic communities of society. Squirting is the product of a maximum climax of pleasure, therefore in sex scenes it is sought for the woman to reach orgasm, an immediate consequence of this pleasure is liquid ejaculation, a cocktail composed of the mucosa that covers the internal walls of the vagina, with a substance similar to semen only present in sexual acts.
When urine appears, it can be a symptom of stress during intercourse, the bladder tenses to the maximum, filling with its maximum capacity with urine and expelling it by the involuntary relaxation of the muscles and the sphincter in orgasm.
The way in which an orgasm is obtained and therefore a Squirting is by stimulating the G-spot, an area of the genital cavity that receives its name from the scientist (Gräfenberg point) who discovered it in which the maximum sexual pleasure is supposedly achieved.
