It does not come from the same place as piss, unless you believe that everything between a woman's legs is one place.
Urine comes from the urethra, which is just below the clit but above the vagina. "Squirt" comes from *within* the vagina. I'm sure we could probably get someone to give you a detailed lesson on female anatomy -- for a modest fee, of course.

The substance could be called quite aptly the female 'prostatae' or 'corpus glandulosum', 'glandulous body'
...The function of the 'prostatae' is to generate a pituito-serous juice which makes women more libidinous with its pungency and saltiness and lubricates their sexual parts in agreeable fashion during coitus.
[VII:81] The discharge from the female 'prostatae' causes as much pleasure as does that from the male 'prostatae'
