Most people with vulvas have the basic anatomy needed to squirt, but whether it happens depends on a mix of anatomical variation, the type of stimulation involved, and how your body responds to arousal. Surveys suggest that somewhere between 40 and 58 percent of women report having experienced squirting or female ejaculation at least once, though many describe it as infrequent and sometimes unexpected. The experience is more common than most people realize, and the science behind it has become considerably clearer in recent years. Understanding what is actually going on in your body can help you recognize the signs.
Squirting and Female Ejaculation Are Not the Same Thing
One of the biggest sources of confusion is that “squirting” and “female ejaculation” get used interchangeably, but researchers now treat them as two distinct events that can happen separately or at the same time. Squirting involves a relatively large volume of clear fluid, typically somewhere around 15 to 900 milliliters, that originates from the bladder. Biochemically, it resembles very dilute urine, with measurable levels of urea and creatinine. Female ejaculation, on the other hand, produces a much smaller amount of thick, whitish fluid, usually just 1 to 5 milliliters, secreted by the Skene’s glands (small structures near the urethra). That fluid is rich in prostate-specific antigen (PSA) and contains almost no urinary markers.
A systematic review and meta-analysis confirmed these distinctions by pooling data across multiple studies. The ejaculatory fluid had a pooled average PSA concentration of about 43 ng/mL and very low urea, while squirting fluid had urea levels comparable to urine and much lower PSA concentrations.1The Journal of Sexual Medicine. Female Ejaculation, Squirting, and Coital Incontinence: A Systematic Review and Meta-Analysis of Biochemical, Imaging, and Urodynamic Diagnostic Criteria Some people experience both simultaneously, which is part of why the two get conflated. If you notice a small amount of milky fluid during orgasm, that is likely ejaculation from the Skene’s glands. If you experience a larger gush of clear fluid, that is squirting proper.
Where the Fluid Comes From
Squirting fluid comes from the bladder. Researchers confirmed this by having participants drink a solution containing blue dye before sexual stimulation. When squirting occurred, the expelled fluid was blue in every case, leaving no real ambiguity about its origin.2PubMed. Enhanced visualization of female squirting Ultrasound studies in other experiments have shown the bladder filling rapidly during arousal and then emptying at the moment of squirting, even when the person had urinated immediately beforehand. The fluid is not straight urine, though. It is significantly more dilute, and in many participants it also contains PSA, which urine collected before arousal does not.3PubMed. Nature and origin of “squirting” in female sexuality
The ejaculatory component has a separate source entirely. The Skene’s glands, located on either side of the urethra, are made of glandular tissue that produces PSA and other markers. Histological studies have shown that these glands are the female equivalent of the prostate, sharing tissue type, enzyme expression, and functional behavior.4PubMed.

Immunohistochemical demonstration One case study documented a woman who could reliably produce both types of fluid separately, with the ejaculatory fluid measuring PSA levels comparable to some components of male semen.5The Journal of Sexual Medicine.

Signs Your Body Might Be About to Squirt
There is no guaranteed checklist, but people who squirt commonly describe a recognizable buildup of sensations. The most frequently reported one is a feeling of pressure or fullness near the front wall of the vagina and around the urethra, similar to the sensation of needing to urinate. This makes sense given what we know about the bladder filling during arousal. Many people reflexively clench or pull back at this point because the sensation is unexpected or because they worry about urinating. Relaxing through that sensation, rather than fighting it, is what people who squirt regularly tend to describe as the turning point.
Other commonly reported signs include a building sense of warmth or swelling in the area behind the pubic bone, a feeling of the pelvic floor muscles bearing down rather than tightening, and a moment where the intensity of stimulation seems to “tip over” into something involuntary. The fluid release itself can range from a small trickle to a forceful gush, and it does not always accompany orgasm. Some people squirt before orgasm, some during, and some without reaching orgasm at all.
If you have noticed occasional wetness during arousal that seems like more than normal lubrication, particularly during intense internal stimulation, you may have already squirted without fully recognizing it. Smaller amounts can be easy to miss or attribute to other sources of moisture.
Why Anatomy Varies So Much Between People
The Skene’s glands are not the same size or configuration in every person. A rapid autopsy study examining tissue from multiple donors found that the distribution of prostatic markers varied considerably. In the lower half of the urethra, glandular structures expressing both PSA and a related enzyme were found in five out of seven donors, while two did not have them at all. Glands in the upper half of the urethra expressed only one of the two markers and were smaller.6PubMed. Distribution of prostatic markers in glands of the female urethra and anterior vaginal wall-a rapid autopsy study This means the glands responsible for producing ejaculatory fluid differ in size, location, and even in whether they are present at all.
Hormonal influences on these glands have not been thoroughly studied, but androgens are suspected to play a role in their development and activity. This might explain some of the variation between individuals and possibly why experiences of ejaculation and squirting seem to change over the course of a person’s life. Some people report first squirting in their thirties or forties, while others describe it happening from their first sexual experiences. There is no reason to assume that the inability to squirt reflects a problem. Some bodies simply have smaller or fewer of the relevant glands, or respond differently to arousal signals.
The Role of Stimulation and the Anterior Vaginal Wall
Researchers have described an area called the clitourethrovaginal complex, which encompasses the clitoris, the urethra, and the front wall of the vagina. These structures are closely connected anatomically, and stimulation of the anterior vaginal wall can simultaneously engage the internal portions of the clitoris and the tissue surrounding the urethra, including the Skene’s glands.7PubMed. Beyond the G-spot: clitourethrovaginal complex anatomy in female orgasm This is the area popularly called the G-spot, though it is better understood as a zone of overlapping structures rather than a single discrete button.
Firm, rhythmic pressure against the anterior vaginal wall, generally a couple of inches inside and toward the belly button, is the type of stimulation most commonly associated with both squirting and ejaculation. This can come from fingers (often in a “come hither” motion), toys designed with a curve, or positions during penetrative sex that angle toward the front wall. Clitoral stimulation alone produces squirting less often, but combined stimulation of both the clitoris and the anterior vaginal wall is what many people describe as most effective. The key variable, though, seems to be sustained pressure and arousal level rather than any specific technique. Rushing or switching approaches frequently tends to work against the buildup.
How Common It Actually Is
The numbers vary depending on how the question is asked and who is surveyed. A U.S. probability sample of women aged 18 to 93 found that about 40 percent had squirted at least once in their lifetime, with a typical frequency of three to five times total.8PubMed. Vaginal Squirting: Experiences, Discoveries, and Strategies in a U.S. Probability Sample of Women Ages 18-93 A Swedish cross-sectional study found a higher figure: 58 percent of respondents reported personal experience with ejaculation or squirting, while 6 percent were unsure whether it had ever happened to them.9Sexual Medicine. Women’s experiences of female ejaculation and/or squirting: a Swedish cross-sectional study Among those with experience, most said it happened only on a few occasions or sometimes, not every time they had sex.
The Swedish study also found that women with non-heterosexual orientations were more likely to have experienced squirting or ejaculation than heterosexual women, at about 63 percent versus 52 percent.9Sexual Medicine. Women’s experiences of female ejaculation and/or squirting: a Swedish cross-sectional study One plausible explanation is that certain sexual activities more common in non-heterosexual encounters, such as manual stimulation of the anterior vaginal wall, are the types most associated with squirting. But other factors like openness to exploration or reduced performance anxiety may also contribute. Either way, the data make clear that squirting is not rare, not limited to a specific demographic, and not something only a small subset of bodies can do.
Telling It Apart from Incontinence
One concern that stops many people from exploring squirting, or from relaxing into the sensations that precede it, is the fear that what they are experiencing is urinary incontinence rather than a normal sexual response. The two can look and feel similar at a surface level, but they are physiologically different. Coital incontinence is a medical condition typically associated with pelvic floor disorders or overactive bladder, and it tends to happen in specific circumstances like during penetration or at orgasm without the characteristic buildup of pleasurable pressure. It is also more common in people who have incontinence at other times, such as during coughing or exercise.10PubMed. Female ejaculation orgasm vs. coital incontinence: a systematic review
Squirting, by contrast, typically occurs in the context of high arousal and sustained stimulation, is usually experienced as pleasurable or at least neutral, and happens alongside other signs of sexual response like engorgement and pelvic muscle engagement. If you are leaking fluid during sex without arousal, without pleasure, or in a way that feels involuntary and distressing, that is worth discussing with a healthcare provider. But if the fluid release happens at moments of peak pleasure and is preceded by that distinctive pressure-and-fullness feeling, the odds are overwhelmingly in favor of it being squirting rather than a bladder problem.
Pelvic Floor Strength and Sensation
Pelvic floor muscles play a supporting role in both sexual sensation and fluid expulsion. Stronger pelvic floor muscles are correlated with better sexual function overall.11PubMed Central. Pelvic floor muscle strength is correlated with sexual function For squirting specifically, some people report that learning to consciously relax and then bear down with the pelvic floor, rather than clenching, is what allows fluid release. This is counterintuitive for many people, because the instinct when feeling that urge-to-urinate sensation is to tighten everything. Practicing awareness of your pelvic floor, being able to both contract and fully release those muscles, may help you recognize and respond to the sensations that precede squirting.
This does not mean that pelvic floor exercises will “make” you squirt. The relationship is indirect. Better muscle awareness gives you more control over what happens during arousal, which can make it easier to lean into the physical cues rather than fighting them. Some people find that after pregnancy or pelvic floor therapy, their experience with squirting changes, either becoming more or less frequent. The pelvic floor is part of the system, not the whole story.
What If It Has Never Happened
If you have never squirted and you are curious about whether you can, the honest answer is that there is no reliable way to predict it from the outside. There is no anatomical self-check, no genetic marker, and no diagnostic test. The wide range in Skene’s gland size and prostatic tissue distribution means that some people may produce very little ejaculatory fluid, while the bladder-origin squirting response seems to depend on a combination of arousal intensity, relaxation, and stimulation type that is difficult to standardize.
What the research does suggest is that the following factors tend to be associated with the experience:
- Sustained anterior wall stimulation: firm, consistent pressure on the front vaginal wall, often combined with clitoral stimulation.
- High arousal before attempting: people who report squirting generally describe it happening after an extended period of buildup, not from cold-start stimulation.
- Relaxation at the critical moment: resisting the urge to clench when that pressure-fullness feeling builds is the most commonly described behavioral factor.
- Comfort and low anxiety: worrying about making a mess or about whether it is “really” urine works directly against the relaxation needed.
Laying down a towel or using a waterproof mattress cover removes one of the biggest psychological barriers. People who squirt regularly tend to describe the same thing: the first time, they did not know what was happening and almost stopped it. Once they understood what the sensation was and stopped fighting it, it became easier to recognize and allow.
A Long History of Mixed Signals
Part of the reason so many people are confused about whether squirting is “real” or what it means is that medicine and culture have gone back and forth on the topic for literally thousands of years. Female ejaculation was well-documented in Chinese Taoist texts as early as the fourth century and described in detail in Indian Kāmaśāstra works starting around the seventh century. In the West, Aristotle mentioned it around 300 B.C., and Galen discussed it in the second century. The first scientific description of female ejaculation and the periurethral glands was written in the seventeenth century by Reinier de Graaf, who called the glands the female prostate.12PubMed. The history of female ejaculation
Despite this long history, the phenomenon was largely dismissed or pathologized through much of the twentieth century, often attributed to incontinence or treated as aberrant. The modern scientific rehabilitation began in the 1980s and has accelerated in the past decade with ultrasound and biochemical studies. The cultural legacy of that dismissal still lingers, though. Many people grow up hearing that squirting is fake, exaggerated by pornography, or a sign of a medical problem. The science does not support any of those positions. It is a real physiological event, it is common, and while the fluid does originate partly from the bladder, it is distinct from incontinence in context, mechanism, and experience.
The Antimicrobial Hypothesis
One intriguing question that remains open is why female prostatic tissue and ejaculatory capability exist at all. One hypothesis proposes that the ability to ejaculate antimicrobial secretions into the urethra during or after sex provided a protective advantage against urinary tract infections, particularly those triggered by intercourse. The reasoning is that women who could flush the urethra with antimicrobial fluid after sex were less likely to develop UTIs, which in turn made them more likely to have frequent intercourse and therefore more likely to reproduce.13PubMed. Does female ejaculation serve an antimicrobial purpose? This remains speculative and has not been tested directly, but it offers a framework for why the Skene’s glands produce the specific secretions they do, including PSA and other enzymes with known antimicrobial properties. The broader squirting response, involving bladder fluid, does not fit as neatly into this hypothesis, and its evolutionary explanation, if one exists, is less clear.
