Sounds like she’s not familiar with modern towel technology :dubious:
She’s an engineer, actually 
She was just self-conscious about it. Just one of those things.
So by what mechanism is it released? Is it simply pressure on the bladder or some kind anatomical variation or something?
The bladder is enervated by both voluntary and involuntary pathways. When stimulated enough, the involuntary pathways are activated to trigger emptying, and overriding them with voluntary signals can be quite the challenge. Nerve conduction studies indicate that both bladder fullness and pelvic engorgement can trigger the involuntary pathways. But pelvic engorgement appears to not trigger them as strongly in all women. Or as strongly every time in the same women. Hence some women squirt a lot, others never do, some do on occasion, others feel like they are about to but shut it down.
At least that’s the operative hypothesis based on what evidence is out there. But let’s face it, medical science is not busy testing thousands of women for their bladder responses during sexual arousal. More focus is placed on treating incontinence, bladder/uterine/ovarian/other cancers, and things that are a threat to health and life.
Or…sex in the shower, or the hot tub. Good clean fun!
I find it fascinating that it took mankind until the 20th century to evolve this uncontrollable involuntary condition. Wow! What capabilities will we evolve in the 21st?
Or maybe nobody found it arousing until porn exploited it as something special we should covet.
All the ancient gazillions of orgasming people in all the continents of the world throughout time had no observation or interest enough to recollect and recount that this ever happened. Not even the cavemen. It took modern American porn to create the fad… Oops, I mean discovery.
And wow, I bet it doesn’t occur in countries where modern American porn is not seen. I wonder if women in Sudan, Papua New Guinea, North Korea, Pakistan, or Botswana can do it? Or is it a unique feature of American anatomy? That would be pretty cool! Does it mean we’re a new species?
Seriously though… It’s urine. This debate belongs on the shelf with Big Foot and psychic powers.
Because pee is yucky and gross and dirty.
(I agree with you intellectually, but it’s hard to get over that programming and enjoy it without shame.)
Everyone’s different, I’m sure, but for my body, it happens with particularly hard fast sex and a really strong orgasm. It really is the blue ribbon in my husband’s trophy case. It is completely involuntary. I’m certain it’s from the bladder, but I do think there’s some mechanism whereby the bladder filling is accelerated. I’ve urinated immediately before sex, totally voided the bladder, and I can still soak a bathtowel 10 minutes later. That’s much more urine than is usually produced per minute. I think that’s why it’s colorless and odorless…it’s mostly water, from the bladder.
There is only one thing a large volume of fluid can be in these cases.
Urine.
More specifically, urine from the kidneys and not from the bladder.
There are no secretory mechanisms in the bladder that can account for this amount of fluid.
Sooner or later someone is going to get some money to study this, if it hasn’t been done so already.
Here is what the conclusion of the paper will say:
“Scientists have finally solved the mystery of “female ejaculation.” In some women, intense sexual excitement suppresses the release of pituitary antidiuretic hormone. This results in a marked increase of free water clearance by the renal nephrons during sexual activity, creating a volume of very dilute urine. At orgasm, there is involuntary relaxation of the bladder sphincter and the urine is released.”
Depending on the newspaper, the headline will be along the lines of:
“Some women pee on their partners, and their partners like it!”
There is no other explanation (aside from regular peeing on your partner during orgasm, but I’m talking about the “I peed right before sex and I still had a huge squirt” crowd).
I have encountered squirters in the past. Put me down as being in the “it is NOT urine” camp. It’s clearly different.
Huh? How does it get to the urethra if not from the bladder?
And I don’t know about you, but that “accelerated filling” of the bladder (or wherever that is happening) can be felt. I feel it clearly. For me, it’s a build up of fluid that happens shortly after an orgasm and from continuous stimulation of the g-spot. In the end, I really don’t think I can explain the sensation well enough to convince anyone of what they already believe, and I really don’t care. And most definitely it is not important. In retrospect, I should have started the thread in MPSIMS, instead. Like you, I also think it’s mostly water. Starting with a half full or empty bladder, makes no difference whatsoever with me. The amount that comes out makes no sense. It just does not equate. Period.
Thanks for participating - those of you who did.
He is, true to name, being pedantic. The urine is made in the kidney, sent through the bladder, and comes out the urethral opening.
Might as well say it comes from the blood, since that’s where the water is before it is filtered out by the kidney, or the large intestine, because that’s when the water is removed from food and put into the blood.
Most people are looking for the large organ immediately preceding the squirt, but we can take it all the way back to this apple I’m about to eat if we like. Probably make some sophomore theology student giddy.
You’re squirting stardust, baby!
This. +1 to your guy for recognizing that it is A Good Thing.
So Chief Pedant would I be correct in saying that basically it boils down to suppression of Anti Diueretic Hormone which would increase Glomerular Filtration Rate in the Kidneys?
This is why the SDMBs are the best on the Internet; if reddit was discussing this, the thread would be full of pop culture references and sophomoric jokes. 4chan would be posting pictures of 13-year-olds squirting. But here at the Dope? We bring the science, bay-bee!
We are stardust.
We are golden.
Caught Point Blank With Squirt Gun…

While part of me can’t believe I’m posting on this topic, I’ve been mussing over my own experiences enough to add to the confusion here.
I have indeed occasionally had excessive liquid appear that I associate as coming from the Skene’s glands. It would occur around ovulation and usually with good oral sex. The liquid is thick, clear to white, and smells nothing like urine. I’ve produced enough of it that standing up can be quite messy. It’s a lovely, sexy fluid and KY can’t begin to compare to how, um, glide-y it is. It feels delicious.
I’ve also had the bladder thing happen. In fact, a full-ish bladder pretty much assures that I am going to have a big orgasm. I will go through a stage where a full bladder can make me horny, just before it gets too full to ignore. I’ve only squirted a couple of times with the overfull bladder. I think it was pee, but it didn’t smell strongly like it. Like Scootergirl, it didn’t feel like I was peeing. But unlike her, my experience of it was so strong it was painful. Really painful. Enough so that I try to avoid it now.
FWIW, I’m a guy, and I find my bladder fills more quickly when I’m sexually aroused.
(And, of course, there’s also the reverse phenomenon, of having an erection when the bladder is very, very full.)
Okay; I read it as if there were some proposed short-cut for urine to go directly to the urethra without ever passing through the bladder. Never mind; just a grammar thing.
(Although, question: how much does the bladder absorb water? Is the bladder a “rubber bag” that expands to hold water, but doesn’t let any pass through the walls? Or do the walls take some water out, filtering it to some degree, saving some for re-use? If so, is this why “old urine” is concentrated and strong and yellow, but “new urine” is fresh and clear? I’ve seen on TV Australian aborigines using kangaroo bladders as water bottles, implying the material is pretty impermeable. But…???)
