Squirting happens when intense stimulation of the sensitive tissue along the front wall of the vagina triggers a release of fluid from the urethra during or just before orgasm. The anatomy responsible centers on a cluster of glandular tissue around the urethra, sometimes called the female prostate, along with the bladder itself. The science has moved past simple “is it pee?” debates, and what researchers have found is more interesting than either side of that argument usually admits.
The Anatomy That Makes Squirting Possible
The key player is a network of small glands surrounding the urethra known as the Skene’s glands, or paraurethral glands. Lab studies using tissue staining have shown that these glands share the same cell markers as the male prostate, and researchers consider them the female equivalent of that organ.1PubMed. Homology between the female paraurethral (Skene’s) glands and the prostate. Immunohistochemical demonstration Like the male prostate, they can produce prostate-specific antigen (PSA) and other secretions. However, their size varies considerably from person to person, and some people have very little glandular tissue while others have a pronounced amount. That natural variation is one reason squirting happens easily for some and not at all for others.
The glands do not work in isolation. Researchers have described what they call the clitourethrovaginal complex, which refers to the way the internal structure of the clitoris, the urethra, and the front vaginal wall all overlap and interact in a shared zone.2PubMed. Beyond the G-spot: clitourethrovaginal complex anatomy in female orgasm When you apply pressure to the front wall of the vagina (what people have long called the G-spot area), you are not stimulating one discrete button. You are pressing against a layered sandwich of erectile tissue, glands, and nerves that all respond together. A review of the research confirmed that orgasm in this area is not produced by a single organ acting alone but by the combined action of multiple tissues working in concert.3PubMed. The relationship between clitourethrovaginal complex and female orgasm
This is why the old search for a “G-spot” as a single anatomical structure kept coming up empty. The sensation people associate with that term comes from the whole complex, and its responsiveness depends on the size of the underlying glands, the density of nerve endings, and how engorged the surrounding erectile tissue becomes during arousal. All of that varies between individuals.
What the Fluid Actually Contains
One of the most persistent questions about squirting is what the fluid is. The honest answer is that it appears to be a mixture of two different substances, and the ratio between them can shift depending on the person and the occasion.
The first component is a small amount of milky or whitish secretion produced by the Skene’s glands. Biochemical analysis of this fluid has shown that it contains PSA and other markers matching what you would expect from prostatic tissue, and it does not resemble urine.4PubMed. The female prostate revisited: perineal ultrasound and biochemical studies of female ejaculate This is what researchers typically mean when they use the term “female ejaculation” in the strict sense. The volume tends to be small.
The second component, which accounts for most of the volume in squirting, comes from the bladder. A study that measured urea, creatinine, and uric acid in squirting fluid found concentrations comparable to what was present in urine samples taken before and after.5PubMed. Nature and origin of “squirting” in female sexuality Another case study noted this same split: one component had features of very dilute urine, while the other showed high levels of PSA similar to what is found in seminal fluid.6PubMed. New insights from one case of female ejaculation
So the answer to “is it urine?” is: partly, but it is not the same as simply peeing. The fluid from the bladder during squirting is significantly more dilute than normal urine, it often contains PSA that urine typically does not, and it is expelled under completely different physiological circumstances. The presence of PSA in this fluid has even raised a practical concern in forensic science, because PSA testing on clothing or bedding is sometimes used to detect semen. Researchers have pointed out that female ejaculate could produce a false positive in those tests.7PubMed. Endogenous female prostate-specific antigen from female ejaculate may confound the use of prostate-specific antigen as a biomarker of exposure to semen
Why the Bladder Fills During Arousal
One of the more surprising findings is that the bladder actively fills during sexual arousal, even if you emptied it right before. Ultrasound imaging studies have captured this in real time, showing the bladder gradually filling as arousal builds and then emptying completely at the moment of squirting.8The Journal of Sexual Medicine. Female Ejaculation, Squirting, and Coital Incontinence: A Systematic Review and Meta-Analysis of Biochemical, Imaging, and Urodynamic Diagnostic Criteria This rapid bladder filling appears to be part of the arousal response itself, likely driven by increased blood flow to the pelvic region and the kidneys speeding up fluid production under the influence of the autonomic nervous system.
This finding explains a common experience: feeling like you need to urinate during intense stimulation of the front vaginal wall, even when you know your bladder was recently empty. That sensation is not your imagination or a sign that something is wrong. It is the bladder rapidly accumulating fluid as part of the arousal process. Many people who squirt report that learning to relax into that “need to pee” feeling rather than clenching against it was the turning point.
How Common Squirting Actually Is
Survey data suggests squirting is far more common than people tend to assume. A cross-sectional study found that roughly 69% of participants reported experiencing some release of urethral fluid related to orgasm.9The Journal of Sexual Medicine. Prevalence and Characterization of Female Ejaculation That number is striking because cultural messaging often frames squirting as rare or exotic. In reality, many people experience some degree of fluid release during orgasm without recognizing it as ejaculation, partly because the volume can be very small and is easily mistaken for increased vaginal lubrication.
The wide range in volume is worth understanding. Some people produce a barely noticeable amount, while others release enough to soak through sheets. Both are within the normal range. The variation likely reflects differences in Skene’s gland size, the degree of bladder filling during arousal, and the intensity of pelvic muscle contractions during orgasm. There is no “correct” amount, and producing more or less does not indicate anything about sexual health or response quality.
Squirting Is Not the Same as Incontinence
Because squirting fluid comes partly from the bladder, it is easy to confuse with stress urinary incontinence, which is involuntary urine leakage during physical exertion or laughter or, yes, sex. Clinicians have emphasized that distinguishing between the two matters, because they arise from completely different mechanisms and have different implications for your health.10PubMed. Female ejaculation orgasm vs. coital incontinence: a systematic review
Coital incontinence typically involves urine loss during penetration or physical effort and is associated with pelvic floor weakness. It is usually not timed to orgasm and often causes distress. Squirting, by contrast, tends to happen at or near the point of orgasm, is associated with high arousal, and in most people is experienced as pleasurable or at least neutral. If you are experiencing fluid loss during sex that feels involuntary, is not pleasurable, and happens independently of orgasm, it is worth discussing with a healthcare provider to rule out a pelvic floor issue. But fluid released at orgasm following intense arousal is overwhelmingly likely to be ejaculation or squirting, not incontinence.
Pelvic Floor Strength and Sexual Response
The pelvic floor muscles play a significant role in both the intensity of orgasm and the mechanics of squirting. Research has found that people who can sustain longer pelvic floor contractions tend to report more consistent orgasms, with measurable differences in contraction duration between those who orgasm and those who do not.11PubMed Central. Pelvic floor muscle strength is correlated with sexual function The pelvic floor muscles wrap around the urethra and vaginal canal, and their rhythmic contractions during orgasm are part of what forces fluid outward.
This does not mean that people with weaker pelvic floors cannot squirt, but building awareness and strength in those muscles can help. Regular pelvic floor exercises (commonly called Kegels) increase both the strength and the voluntary control of these muscles. Greater control means you can more effectively relax them when you feel the urge to bear down during arousal, which is often necessary for squirting. Paradoxically, the skill is not about squeezing harder during orgasm but about being able to consciously release and push outward at the right moment.
Practical Tips for Experiencing Squirting
If you are curious about squirting and want to explore it, the anatomy and physiology outlined above point to a few practical strategies.
- Empty your bladder first: This reduces anxiety about whether you are going to urinate. Remember, the bladder will partially refill on its own during arousal anyway, so emptying beforehand mainly helps you relax.
- Focus on the front wall: Using fingers or a curved toy, apply firm pressure toward the front (belly-button side) of the vaginal wall, about one to three inches inside. This is where the clitourethrovaginal complex is most accessible. A “come hither” motion with the fingers is the classic approach because it creates rhythmic pressure against that tissue.
- Build arousal first: The glandular tissue and erectile structures in the complex need time to engorge with blood. Jumping straight to internal stimulation without adequate arousal often feels uncomfortable rather than pleasurable. External clitoral stimulation beforehand helps bring blood flow to the whole area.
- Relax into the sensation: When stimulation of the front wall builds toward a peak, many people feel a strong urge that resembles needing to urinate. The instinct is to clench and hold back. Squirting typically requires you to relax the pelvic floor and gently bear down instead. Laying down a towel or waterproof pad beforehand removes the practical worry that makes this harder to do.
- Do not treat it as a goal: Pressuring yourself or a partner to squirt can create performance anxiety that works against the relaxation you need. Approaching it as exploration rather than achievement tends to produce better results and a better experience regardless of outcome.
Partner communication matters here too. If a partner is providing stimulation, feedback about pressure, speed, and angle is essential because the anatomy varies enough between people that there is no universal technique. What works perfectly for one person may do nothing for another.
When Squirting Does Not Happen
Plenty of people try everything above and still do not squirt, and that is completely normal. The variation in Skene’s gland size alone means some people may not have enough glandular tissue to produce a noticeable volume of fluid. Others may have glandular tissue that drains internally into the urethra rather than being expelled outward. Some people find that squirting happens easily in one phase of life but not another, possibly related to hormonal changes affecting tissue engorgement and fluid production.
Medication can also play a role. Anything that affects fluid balance (diuretics, for example) or nervous system response (certain antidepressants, antihistamines) could theoretically alter the body’s ability to produce the arousal-related bladder filling that contributes to squirting volume. There is limited formal research on these specific connections, but the underlying physiology makes it plausible.
The most important thing to understand is that squirting is neither a measure of sexual satisfaction nor a necessary component of a fulfilling sex life. Orgasm can be intensely pleasurable with or without fluid release. Treating squirting as the gold standard of sexual response creates unnecessary pressure and misrepresents what the research actually shows about the diversity of normal sexual function.
An Antimicrobial Theory
One intriguing question is why the female prostate tissue persists at all from an evolutionary standpoint, given that it has no role in reproduction. One hypothesis proposes that the secretions from the Skene’s glands may have an antimicrobial function, flushing protective compounds including zinc into the urethra during and after intercourse.12PubMed. Does female ejaculation serve an antimicrobial purpose? The reasoning is that sex-related urinary tract infections are common, and a mechanism that bathes the urethra in antimicrobial fluid right when bacteria are most likely to be introduced would confer a survival advantage. People who could clear those bacteria would stay healthier, have sex more frequently, and reproduce more successfully.
This remains a hypothesis rather than an established fact. The zinc content of female ejaculate has been measured, and the logic is consistent with what we know about male prostatic fluid (which does serve an antimicrobial role). But controlled studies directly testing whether people who ejaculate experience fewer UTIs have not been conducted. It is a plausible idea that awaits harder evidence.
Centuries of Documentation
Female ejaculation is not a modern discovery, despite often being treated as one. Writings about it appear in Chinese Taoist texts from the fourth century, in Indian texts of the Kamasutra tradition from the seventh century onward, and in Western sources dating back to Aristotle around 300 BCE.13PubMed. The history of female ejaculation The Dutch physician Reinier de Graaf provided the first detailed anatomical description in the seventeenth century and was the first to identify the periurethral glands as the female prostate.
The phenomenon went through a long period of medical denial in the twentieth century, when female ejaculation was routinely dismissed as incontinence or fabrication. Its rediscovery in modern sexology has been gradual and is still incomplete. Many healthcare providers receive little or no training on it, which is one reason people who squirt sometimes encounter dismissive or confused reactions from their doctors. The historical record is a useful corrective: cultures around the world recognized and documented this experience for thousands of years before modern medicine briefly forgot about it.
