Squirting is the involuntary release of fluid through the urethra during sexual arousal or orgasm. It’s a normal physiological response that some women experience, though it remains one of the more misunderstood aspects of female sexuality. The fluid, the source, and even how common it is have been subjects of scientific debate for years, but recent research has clarified much of the picture.
Squirting vs. Female Ejaculation
One of the biggest sources of confusion is that squirting and female ejaculation are often used interchangeably, but they are two distinct phenomena that can happen separately or at the same time.
Squirting involves a larger volume of fluid, typically 10 milliliters or more, that is thin and transparent. This fluid comes from the bladder and has a chemical profile similar to diluted urine, containing urea, creatinine, and uric acid at concentrations comparable to what you’d find in a urine sample.
Female ejaculation, by contrast, produces only a few milliliters of thick, milky fluid. This fluid originates from the Skene’s glands (sometimes called the female prostate), two small structures located near the urethral opening. It contains high concentrations of prostate-specific antigen, or PSA, a protein also found in male semen. In one detailed case study, ejaculatory fluid contained PSA at roughly 4,000 ng/mL, a level that confirms it’s biochemically closer to prostatic secretion than to urine.
In practice, many women who squirt release a mix of both fluids. Ultrasound studies of women just before and after squirting found that PSA, which was absent from urine samples taken before arousal, showed up in the squirting fluid of five out of seven participants. So while the bulk of the liquid comes from the bladder, secretions from the Skene’s glands often contribute.
Where the Fluid Comes From
Ultrasound imaging has given researchers a clear picture of what happens inside the body during squirting. In studies where women’s bladders were scanned at three points (after emptying, during arousal, and after squirting), a consistent pattern emerged. The bladder was confirmed empty at the start. During sexual stimulation, it rapidly refilled. After squirting, it was empty again.
This rapid filling is notable because it happens much faster than normal kidney function would explain, suggesting the body diverts fluid into the bladder during arousal through mechanisms that aren’t fully understood yet. The fluid is then expelled involuntarily through strong contractions of the pelvic muscles. Imaging has captured rhythmic contractions repeating around 20 times over about 60 seconds during this process, with an estimated 100 milliliters of fluid leaving the bladder in some cases.
How Common It Is
Estimates vary widely depending on how the question is asked. The International Society for Sexual Medicine cites a prevalence of about 5% for squirting as a regular occurrence. But when researchers cast a wider net, the numbers are higher. A Swedish cross-sectional study found that 58% of participants had experienced squirting or ejaculation at least once, though only 7% said it happened consistently. For the majority (52%), it had occurred on just a few occasions.
The same study found the experience was significantly more common among non-heterosexual women, possibly reflecting differences in sexual practices or comfort with exploration. About 61% of women who had squirted reported that orgasm occurred close to or at the same time, and those women were more likely to view the experience positively.
What Triggers It
There’s a widespread belief that squirting requires stimulation of the front wall of the vagina (the area sometimes called the G-spot). Recent research challenges this. The Swedish study found that clitoral stimulation alone can trigger squirting, meaning there isn’t one specific technique or type of touch required.
The response appears to be involuntary. It can happen before, during, or after orgasm, and many women describe it as something they don’t consciously control. The physical mechanism involves strong pelvic floor contractions that expel fluid from the bladder through the urethra, similar in mechanics (though not identical) to what happens during orgasm more broadly.
How Women Feel About It
Reactions to squirting are mixed, and not always positive. In the Swedish study, 58% of women who had experienced it reported wanting to avoid it at some point. The most common reasons were the amount of wetness it produced and anxiety about whether the fluid was urine. That insecurity often stems from a lack of clear, honest information about what squirting actually is.
Women who experienced squirting alongside orgasm were more likely to rate it positively, suggesting the context matters. When it feels connected to pleasure, it tends to be welcomed. When it feels unexpected or unexplained, it can cause embarrassment or worry.
Is It Normal?
Squirting is a normal physiological variant of sexual response. It is not a sign of urinary incontinence, a medical problem, or anything that needs treatment. The fluid does share chemical markers with urine because it originates in the bladder, but the mechanism is distinct from losing bladder control. It involves a specific pattern of rapid bladder filling during arousal followed by involuntary expulsion during the muscular contractions of sexual response.
The scientific understanding is still catching up to the experience. Squirting has been described in medical literature for centuries, but rigorous studies using modern imaging and biochemical analysis only began in the last decade or so. What’s clear is that it’s a real, measurable event with identifiable anatomy behind it, not something invented or exaggerated. Whether you experience it or not has no bearing on sexual health or function.
