Roughly 5% to 40% of women have experienced squirting, depending on how the question is asked and which study you look at. That wide range reflects real differences in methodology: clinical estimates based on observed physiology put the figure closer to 5%, while self-reported surveys return much higher numbers. A nationally representative U.S. survey found that 40% of adult women said they had squirted at least once in their lifetime, with a median frequency of three to five times total. A Swedish cross-sectional study found 58% of participants reported experiencing ejaculation or squirting. The gap between these numbers tells you something important: this is a topic where definitions, memory, and interpretation of what “counts” vary enormously.
Why the Numbers Vary So Much
The biggest source of confusion in the research is that “squirting” and “female ejaculation” are two distinct physiological events that often get lumped together. Squirting involves a larger volume of transparent fluid, typically 10 milliliters or more, expelled through the urethra. Female ejaculation is a much smaller secretion of thick, milky fluid from the Skene’s glands, two tiny structures flanking the urethra. Both can happen during arousal or orgasm, and they can occur at the same time, which makes survey responses unreliable unless the questionnaire carefully distinguishes between the two.
Older studies from the 1980s and 1990s asked about “orgasmic expulsion of fluid” without specifying type. One found that 54% of 227 women had experienced it at least once. Another found 40% reported a fluid release at the moment of orgasm. These numbers likely capture a mix of squirting, ejaculation, and normal arousal lubrication. The 5% estimate from the International Society for Sexual Medicine reflects a narrower, more clinically defined version of squirting as a distinct event rather than any fluid release during sex.
What Squirting Actually Is
The fluid expelled during squirting comes from the bladder. This has been confirmed directly: in one study, researchers inserted a catheter, emptied participants’ bladders, then injected a blue dye solution. After sexual stimulation led to squirting, the discharged fluid was blue in every case. The bladder fills rapidly during arousal and empties during the event.
Chemically, squirting fluid contains urea and creatinine, the same waste products found in urine, but at diluted concentrations that vary from person to person. It also contains small amounts of prostate-specific antigen (PSA), a protein produced by the Skene’s glands. This suggests the fluid is a mix: primarily dilute bladder contents with some contribution from the Skene’s glands. It is not the same as urine in the conventional sense, but it is not entirely separate from it either.
Female ejaculation, by contrast, is a smaller volume of thicker, whitish fluid that originates from the Skene’s glands themselves. These glands develop from the same embryonic tissue as the male prostate, which is why they’re sometimes called the “female prostate.” They swell during arousal as blood flow increases, and they secrete fluid that contains proteins similar to those found in male semen. The Skene’s glands are about the size of a small blueberry, though their size varies between individuals, which may partly explain why some women experience ejaculation and others do not.
What Triggers It
Stimulation of the area commonly called the G-spot is the most frequently reported trigger. This isn’t a single anatomical structure but a sensitive zone on the front wall of the vagina where several tissues converge: the internal structure of the clitoris, the Skene’s glands, and the urethra. When this area is stimulated, the surrounding tissues swell, and in some women this leads to ejaculation, squirting, or both. Beverly Whipple, the researcher who popularized the term “G-spot,” has described it as “an area that is extremely sensitive” where “some experience female ejaculation when stimulating this area.”
Not all squirting happens during orgasm. Research has found that among women who have squirted, roughly equal numbers said squirting always accompanied orgasm as said the two never occurred together. This lines up with the broader finding that squirting can happen independently of orgasm, during arousal alone.
How Women Experience It
Among women who have squirted, the experience is more commonly described as moderately pleasurable than intensely so. In a U.S. survey, about 52% described squirting as “a little” or “somewhat” pleasurable, while 34% called it “very” pleasurable. The remaining women were neutral or found it unpleasant, often due to embarrassment or concern about the fluid itself.
For most women who do experience it, squirting is infrequent. The median in the U.S. survey was three to five times over a lifetime. A small subset of women squirt regularly or during most sexual encounters, but this appears to be uncommon. The variation likely comes down to individual anatomy, particularly the size and responsiveness of the Skene’s glands, the sensitivity of the anterior vaginal wall, and how the bladder responds to arousal.
Squirting vs. Urinary Incontinence
Because squirting fluid comes partly from the bladder, there’s an obvious overlap with coital urinary incontinence, which is involuntary urine leakage during sex. The International Continence Society considers these pathophysiologically distinct: squirting is a normal physiological response tied to high arousal, while coital incontinence is a symptom of pelvic floor dysfunction or bladder control issues. In practice, the two can look similar, which is why some researchers emphasize that fluid expulsion during sex should not automatically be treated as a medical problem.
The key differences are context and pattern. Squirting typically occurs at moments of peak arousal or orgasm, involves fluid that is more dilute than normal urine, and is not associated with other urinary symptoms. Coital incontinence tends to happen during penetration (from physical pressure on the bladder) or at orgasm in women who also experience leakage during coughing, sneezing, or exercise. If fluid loss during sex is accompanied by other signs of bladder control issues, that points toward incontinence rather than squirting.
