What do girls mean by "squirting

Squirting is another name for female ejaculation and means during sexual stimulation to the right area and the ability to be able to relax fully and let pleasure take over you get the feeling of needing to pee but once you master the art what actually comes from your urethra is a clear odourless fluid. Some females actually squirt hard as in a real jet some just get a little trickle.
Female ejaculation mainly occurs through gspot stimulation rather than clitoral stimulation.
I hope this answers your questions but if you have more just contact me and i will try to explain hun :-)

Girls refer to an sexual-stimulation-related expulsion of fluid from their genital region as 'squirting'. Sometimes it is vaginal gushing; sometimes it is urethral squirting, and is female ejaculation. This is not urine (although some girls do squirt pee when stimulated). Quite often it is related to orgasm following stimulation that has included the 'g-spot' as well as the clitoris.

Remember that girls often exaggerate their experiences, or even invent them to show-off. Also, each person is different, and responds differently to touch. So a girl could be referring to an ejaculation or to urination, but probably trying to convey the idea of orgasmic ejaculation.

The ejaculated fluid comes from the paraurethral ducts close to the urethra during or before an orgasm.

Hope this helps
