Squirting is the expulsion of fluid from the urethra during sexual arousal or orgasm. It happens because the bladder rapidly fills during stimulation and then releases its contents involuntarily, often alongside a small amount of fluid from glands near the urethra. The experience is normal, varies widely from person to person, and is more common than many people assume.
Squirting and Ejaculation Are Two Different Things
One of the biggest sources of confusion is that “squirting” and “female ejaculation” are often used interchangeably, but researchers now treat them as distinct events that can happen separately or at the same time.
Female ejaculation is the release of about 1 milliliter of thick, whitish fluid from the paraurethral glands, also called Skene’s glands. These small glands sit on either side of the urethra and develop from the same embryonic tissue that becomes the prostate in males. The fluid they produce contains prostate-specific antigen (PSA), fructose, and glucose, giving it a composition surprisingly similar to seminal fluid.
Squirting, by contrast, involves a much larger volume of clear fluid, anywhere from tens to hundreds of milliliters, released from the urethra during high arousal or orgasm. This is the dramatic gush most people picture, and its origin is different from the small milky secretion of true ejaculation.
Where the Fluid Comes From
Ultrasound studies have traced squirting fluid directly to the bladder. In one widely cited study, researchers scanned seven women at three points: after they emptied their bladders, during sexual stimulation just before squirting, and immediately after. The scans showed that the bladder refilled noticeably during arousal, then emptied again when squirting occurred. The fluid, in other words, accumulated in the bladder during stimulation and was expelled from there.
Chemical analysis backs this up. The large volume of clear fluid contains urea, creatinine, and uric acid, all markers of fluid produced by the kidneys and stored in the bladder. But it isn’t simply urine. In several of the women studied, the squirted fluid also contained small amounts of PSA that were not present in their urine samples collected before the study began. This suggests that secretions from the Skene’s glands mix into the fluid as it passes through the urethra, meaning squirting and ejaculation can overlap in a single event.
The Role of the Skene’s Glands
The Skene’s glands are the key to the ejaculation component. Sometimes called the “female prostate,” they share a developmental origin with the male prostate and produce similar biochemical markers. During arousal, these glands can secrete a small quantity of milky fluid rich in PSA. Because the glands drain into the urethra, their secretion can be expelled on its own or carried along with the larger volume of squirting fluid.
Skene’s glands vary in size from person to person. Some women have relatively prominent glands, others have very small ones, and this anatomical variation likely plays a role in whether someone experiences ejaculation, squirting, both, or neither.
How Common Is It?
Survey data on prevalence varies widely depending on how the question is asked. In one population-based survey, 54% of 233 women reported a spurt of fluid at orgasm. A larger mail survey of over 1,100 women found that about 40% identified as ejaculators. Other estimates run much lower: one study of 300 women put the figure at under 5%. The broad range reflects differences in definitions, survey methods, and whether women recognize or report the experience. Overall, researchers estimate that fewer than half of women ejaculate or squirt during sexual activity, but it is far from rare.
Many women who do experience it report that it doesn’t happen every time. It can depend on the type of stimulation, level of arousal, hydration, and individual anatomy. Some notice it only during particularly intense orgasms or with specific kinds of pressure on the front vaginal wall, near where the Skene’s glands and surrounding nerve-rich tissue sit.
Why It Feels Involuntary
Squirting typically happens without conscious effort. The pelvic floor muscles contract rhythmically during orgasm, and these contractions can create enough pressure to push fluid from the bladder and urethra. Many women describe a sensation similar to needing to urinate just before it happens, which makes sense given that the fluid is collecting in the bladder. The similarity to that feeling leads some women to hold back, but the fluid’s composition is dilute compared to regular urine, and it often contains the additional glandular secretions that distinguish it chemically.
The involuntary nature is part of why squirting can catch people off guard. It is not something most people can train themselves to do or prevent reliably. Relaxation and comfort during arousal tend to make it more likely, while tension or self-consciousness can suppress it.
Is It Normal?
Squirting is a well-documented physiological response with no associated health risks. Large surveys consistently show that women who experience it, and their partners, tend to view it positively. It does not indicate a medical problem, nor does the absence of squirting suggest anything is wrong. The variation comes down to anatomy, arousal patterns, and individual physiology. Whether it happens frequently, rarely, or never, all of these fall within the normal range of sexual response.
