Well, it’s a lot more complicated than a simple yes or no question. First of all, squirting and female ejaculation are actually two different things. Squirting is the expulsion of a substance containing urine, among other things, from the urethra during an orgasm, while female ejaculation is the expulsion of a different substance, closer in composition to semen and vaginal fluid, from the Skene’s glands, located near the urethra and often thought of as the “female prostate”. Both are the result of intense sexual stimulation and orgasms due to G-spot stimulation, although female ejaculation by itself is much more common, with squirting being much more obvious and messy.
So yeah, squirting is kinda pee, but also not really.
The only issue I’ve seen is that too much friction on the G-spot can cause uncomfortable abrasions. From the ejaculations themselves, it doesn’t seem to have caused any problems. Maybe dehydration?
I’m more thinking more along the lines of “is propensity for squirting correlated with pelvic floor weakness/issues, and should this be brought up with a partner as food for thought/for discussion with a doctor to keep an eye on things”.
But then my mind usually wanders to other stuff.
I haven’t seen anything in practice or online that would suggest that squirting is indicative of any pelvic floor issues. There is such a thing as coital incontinence, which is a separate issue.
