Keep the anecdotes cuming.
Well, not nothing but urine. Just mostly urine, with some other secretions.
I can never know what a woman’s body feels…but for guys, urinating while highly sexually aroused is quite different from urinating in more ordinary circumstances. It can be done, but it takes effort, and is not comfortable. But, even so, some men do urinate, copiously, along with ejaculation. It’s just something that their bodies have worked out.
(I read about this in an interview with a porn star, who does it deliberately because it increases fluid volume, and that looks good on camera. Ew.)
Is it possible that something like this is in play with women? Urination while highly aroused is maybe different from urination at any other time? A pen-pal of mine says that, for her, sex is better when the bladder is about half-full. But is that usual, or rare?
(“Yvette! Into the lab! Research must be performed!” “Oh, doctor! Again?”)
I retract this claim. Thanks gang and ignorance fought.
From samclem’s link: [INDENT] 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.[/INDENT] I find it plausible that a marginal contribution of prostatic secretions could be pleasurable.
Try pre-loading the bladder with blue dye. Then run the test and see if the fluid is still colorless.
I can tell you this much for sure: it is by no means involuntary.
Does anyone have an idea of the percentage of women who squirt? “Women who squirt” is really the denominator we want here, not “all women”.
Sure it is, but is it definitive? I mean, I’m obviously leaning toward the bladder/urine explanation, but I was expecting a study of more than a handful of women.
19%. Ok that’s from my relatively small sample size but hey, it’s a number.
It seems quite plausible to me that there might be two different phenomena, here, which are lumped together only because they’re hard to distinguish in uncontrolled circumstances. Like, there might be some women who “squirt” perhaps a teaspoon of genuine ejaculatory fluid secreted directly from a small gland, and some other women who “squirt” a small (but much larger than above) amount of genuine urine when aroused, and yet other women who do a combination of both, either at the same time or on different occasions. One cannot say “some squirts are too large in volume to be ejaculatory fluid, and therefore no squirt can be ejaculatory fluid”.
The alternative is that there is another organ/structure/mechanism in the female pelvis that has gone undetected by science for centuries. That’s a rather extra-ordinary claim, and those making the claim need to provide the extra-ordinary evidence.
As opposed to our working hypothesis: What’s shooting out of the urethra during female sexual arousal is urine, possibly with a few extra secretions added. There’s a large body of evidence for that.
How much more do we need to study the question? I’d say that unless someone provides solid scientific evidence to the contrary, we can choose to turn our attention to other things.
I mean, do we need to turn over every rock in the garden to prove that Elvis is not living under a rock in the garden? If turning over a few dozen rocks turns up his driver’s license, maybe we’d better turn over some more. But otherwise I’m satisfied that the evidence so far strongly implies he’s not there.
We haven’t determined yet if said female ‘ejaculatory fluid’ exists as its own particular entity the way male ‘ejaculatory fluid’ does. No one competent denies that aroused women can produce a lot of fluids (including a fluid containing PSA among other things), nor that muscle contractions (voluntary or involuntary) can propel fluids. There’s no doubt that small amounts of fluid can be expelled from the vagina during arousal and at orgasm. But should it be classified as a unique fluid? As an ejaculate?
Meanwhile, evidence indicates that the large volumes of fluid emitted from the female urethra during arousal/orgasm comes mainly from the bladder.
And if it’s coming from the bladder, it’s an ultra-filtrate of the blood produced in the kidneys, meaning urine. Barring anatomical abnormality like recto-vesicular fistula or other abnormal communications into the bladder.
The most closely controlled (for randomness and to avoid self-selection) scientific surveys generally have the number at 10% or less. Less rigorous ones have numbers as high as 40%.
I would like to conclude with something my guy has said, “I don’t care what it is or where it comes from. I love it. Can we do that again, please?”
What I want to know is how to prevent it from happening without having to give up sex or orgasming (although it’s been so long now I’m beginning to forget what it’s like . . . But that’s for a different thread). Anyway, I am a squirter and hate it. It’s messy, embarrassing and the guys I’ve been with did not find it arousing. 
Further anecdotage to follow:
Prior to 2008, I had never been with a woman who squirted. Since 2008, I haven’t been with a woman who DIDN’T squirt. Granted, this is a small sample size of three before and five after.
Of the squirters, it was almost definitely (predominantly) urine in four of them - at least as far as I can tell. In the fifth, however, the substance was indistinguishable from precum, and much smaller in volume - about what I’d ejaculate with a day’s rest. In her case, I could feel the area I associated with her Skene’s glands swollen if we hadn’t made love in a while; admittedly, this was subjective.
I’d say the study Samclem cited is in line with my experience. My hypothesis is that a lot of women experience rapid bladder filling and emptying when making love, especially when the vaginal nerve endings around the bladder are stimulated, and that’s the supermajority of what we call squirting. I would say there’s something else going on in some women, though. I reckon the precum-squirter* I was with is analogous to the one subject in the Salama, et. al. study whose leavings yielded evidence of PSA, with the caveat that she probably wasn’t urinating at the time; her fluids were extremely silky, unlike the more watery stuff I’ve elicited.
The above isn’t science by a long shot, but it’s my experience.
*She would be laughing hysterically to find herself described that way.
Seconded. Man after my own heart. Sounds like you’ve got yourself a keeper there.
I’ve talked with a woman who feels the same way. She’s a virgin who’s never had an orgasm masturbating because she feels like she will wet the bed. Not sure what to say about that.
Now where is big bettin’ Bricker when we need him?
I’m really not arguing with any of that. I just thought that they could round up another couple dozen women, if they’re going to bother with a study.
I didn’t claim that we had. I was merely pointing out the possibility. Maybe it doesn’t exist, but we haven’t yet proven that it doesn’t exist.
And women certainly have some organ which produces PSA, which can then find its way into the stream somehow. Presumably, this organ is the Skene’s gland, which is known to modern anatomy. And while the secretions from Skene’s gland can be mixed with urine, maybe they can also be emitted on their own?
Proving a negative is rather tough. How far should we try to go to do that?
I’m sure they’re emitted and not mixed with urine when urine is not present. But again the problem is volume. There’s no sign of any sizeable reservoir to hold skene’s gland secretions in the volume needed to produce such a squirt. And claims that the Skene’s gland can produce such copious amounts of fluid so rapidly remain unsubstantiated. Evidence so far indicates that they don’t work that fast.
Hey, I’m open to new evidence. I just don’t understand why so many people want to reject the idea that squirting is coming mainly from the bladder, when our best info indicates that it is. If it’s fun, just enjoy it!
