BSU = Before Sexual Stimulation Urine

(Ie, they had them pee in a bottle before hand)

S = The actual ‘squirt’ liquid

ASU = After Sexual Stimulation Urination

(pee in a bottle again after squirting)

PSA = Prostate Secreted Antigen

(where Skene’s gland is also known as “the female prostate”)

Results

…

Biochemical analysis of BSU, S, and ASU showed comparable urea, creatinine, and uric acid concentrations in all participants. Yet, whereas PSA was not detected in BSU in six out of seven participants, this antigen was present in S and ASU in five out of seven participants.

Conclusions

The present data based on ultrasonographic bladder monitoring and biochemical analyses indicate that squirting is essentially the involuntary emission of urine during sexual activity, although a marginal contribution of prostatic secretions to the emitted fluid often exists.

Results

In this case report, we provided new biochemical evidences demonstrating that the clear and abundant fluid that is ejected in gushes (squirting) is different from the real female ejaculation. While the first has the features of diluted urines (density: 1,001.67 ± 2.89; urea: 417.0 ± 42.88 mg/dL; creatinine: 21.37 ± 4.16 mg/dL; uric acid: 10.37 ± 1.48 mg/dL), the second is biochemically comparable to some components of male semen (prostate‐specific antigen: 3.99 ± 0.60 × 103 ng/mL).

Conclusions

Female ejaculation and squirting/gushing are two different phenomena. The organs and the mechanisms that produce them are bona fide different. The real female ejaculation is the release of a very scanty, thick, and whitish fluid from the female prostate, while the squirting is the expulsion of a diluted fluid from the urinary bladder.

https://en.wikipedia.org/wiki/Skene's_gland

In female human anatomy, Skene’s glands or the Skene glands (/skiːn/ SKEEN, also known as the lesser vestibular glands or paraurethral glands[1]) are two glands located towards the lower end of the urethra. The glands are surrounded by tissue that swells with blood during sexual arousal, and secrete a fluid, carried by the Skene’s ducts to openings near the urethral meatus, particularly during orgasm.

…

In an amount of a few milliliters, fluid is secreted from these glands when stimulated from inside the vagina.[9][10] Female ejaculation and squirting (secretion of large amounts of fluid) are believed by researchers to be two different processes. They may occur in combination during orgasm. Squirting alone is a sudden expulsion of liquid that at least partly comes from the bladder and contains urine, whereas ejaculation fluid includes a whitish transparent ejaculate that appears to come from the Skene’s gland.[3][11]

So, if I am understanding this all correctly, a diluted urea concentration is what you would normally expect from basically urine.

“Squirting” just is primarily urine, a release of urine from the bladder, through the urethra, though it seems it can have a bit more substances from the female prostate / Skene’s gland mixed in with it than normal urine.

The uh, openings or exit points of the Skene’s gland are apparently on either side of or around the exterior opening of the urethra.

Then you also have the Bartholin’s glands, which apparently ‘exit’ around the ‘bottom’ of the vagina.

And the Skene and Bartholin’s glands both secrete, enlarge, and emit different kinds of liquids with specific chemical signatures when a woman is highly aroused / orgasming.

So… perhaps this has something to do with different ‘kinds’ of orgasms women can experience… I imagine it would or could feel physically different if different parts of your body are differently enlarged and then discharging.

There is apparently a distinct phenomenon of actual ‘female ejaculation’, but this does not primarily come from the urethra.

This seems to be a sudden and substantial sort of emptying of all of that vaginal lubricant supplied by the Skene’s glands / female prostate, possibly also the Bartholin’s glands, that all happens rather rapidly, is milky and viscous like male semen, and does not come out of the urethra.

So, normally, this is the stuff that uh, ‘leaks’ from a highly aroused, “wet” vagina, but in some cases… apparently it just all comes out at once, as opposed to like a steady drip feed.

Personally, … I think I may have seen something like that a number of times.

I… have been with women / had specific encounters where there was considerably more, and considerably more ‘milky’ liquid than what I would call ‘normal’, where normally its more clear, less substanial.

I do not know if it was … all discharged at once though.

So uh… seeing as even ‘science’ barely understands what the fuck is going on here, maybe you could comment on your experiences with this?

Have you ever had a much more substantial and milky uh, female ejaculation from the vagina, as opposed to a ‘normal’ amount of just being aroused and wet?

That seems to happen fairly rapidly, or… maybe is more volume than normal, but over a sustained period of time?

Does that coincide with a different ‘kind’ of orgasm?

Please, for science!
