We've got a site that features it (
Squirt Hunters). As far as whether or not squirting is real...I've slept with two girls that I would say "gushed" more than "squirted". The first time it happened I wasn't entirely sober and was convinced she had just pissed on me until it dawned on me that it didn't smell like urine, lol
I do think a lot of it in porn is faked. It looks like they're urinating all over the place.
