Female cum is fluid released from the body during sexual arousal or orgasm, but the term covers two distinct phenomena that researchers have only recently begun to tease apart. One is a small volume of thick, milky secretion produced by glands surrounding the urethra. The other is a larger gush of dilute fluid that comes primarily from the bladder. Most people use “female cum,” “female ejaculation,” and “squirting” interchangeably, but the science suggests they are not the same thing, and understanding the difference clears up a lot of confusion about what the fluid actually is and where it originates.
Two Types of Fluid, Two Different Sources
The single biggest source of confusion in this area is that “female ejaculation” and “squirting” get treated as synonyms when they appear to be separate events with different origins. Female ejaculation in the narrow, clinical sense refers to a relatively small amount of whitish, viscous fluid that comes from the paraurethral glands, also called Skene’s glands. These tiny glands sit on either side of the urethra and share a developmental origin with the male prostate. Research using tissue staining techniques has confirmed that Skene’s glands and the prostate are structurally and functionally homologous, meaning they derive from the same embryonic tissue and produce some of the same substances.1PubMed Central. Homology between the female paraurethral (Skene’s) glands and the prostate. Immunohistochemical demonstration
Squirting, by contrast, involves a much larger volume of clear, watery fluid. A study that tracked seven women using pelvic ultrasound before and during sexual stimulation found that the bladder filled rapidly during arousal and then emptied at the moment of squirting. Biochemical analysis of the expelled fluid showed it was chemically close to dilute urine, though in five of the seven women, trace amounts of prostate-specific antigen (a marker of Skene’s gland secretion) were also present. The researchers concluded that squirting is essentially an involuntary release of urine during sexual activity, with a small contribution from prostatic secretions mixed in.2Wiley Online Library. Nature and origin of “squirting” in female sexuality
So the short version: ejaculation produces a small amount of glandular fluid from Skene’s glands, and squirting produces a larger volume of bladder-derived fluid. In practice, many people experience both at the same time, which is why the mixture looks and feels different from plain urine and why the question of “what is it really?” has stayed contentious for so long.
What Is in the Fluid
The chemical makeup of the glandular component has been analyzed in several small studies, and it looks quite different from urine. Compared to urine collected from the same individuals, female ejaculate had lower levels of creatinine, which is a standard waste product in urine, while showing elevated levels of prostate-specific antigen and prostatic acid phosphatase, both of which are enzymes associated with prostate tissue.3Elsevier. Does female ejaculation serve an antimicrobial purpose? Glucose levels were also higher in the ejaculate than in urine. The presence of PSA is particularly telling because it confirms that Skene’s glands are actively secreting their own product, not just channeling urine.
The squirting component, as noted above, has a chemical profile much closer to very dilute urine. It contains urea and creatinine but at lower concentrations than a typical urine sample, which makes sense if the bladder is filling and emptying rapidly during arousal rather than going through the normal hours-long cycle of urine production. The PSA traces found in squirting fluid in some women suggest the two fluids mix on their way out, since they share a common exit through the urethra.
One hypothesis that has circulated in the literature is that the prostatic secretions in female ejaculate could serve an antimicrobial purpose, similar to how some components of seminal fluid in men have antibacterial properties. This idea remains speculative, but the biochemical profile of the fluid at least makes it plausible.
Where It Comes From Anatomically
Skene’s glands are the main source of the ejaculate component. They are embedded in the tissue surrounding the urethra, and their ducts open into the urethral canal near its external opening. Their size varies substantially from person to person, which likely explains some of the wide variation in how much fluid people produce and whether they experience noticeable ejaculation at all. Some anatomical studies have found that a small percentage of women have very underdeveloped or even absent Skene’s glands.
The glands are part of a broader anatomical region that researchers now refer to as the clitourethrovaginal complex. This is the cluster of erectile tissue, glands, and nerves that sits between the vaginal wall and the urethra, and it includes the internal portions of the clitoris, the urethral sponge, and Skene’s glands. Stimulation of the front vaginal wall activates this complex as a whole rather than hitting a single, discrete “G-spot.” Research on female orgasm and ejaculation has emphasized that orgasm from vaginal penetration is best understood as stimulation of this entire complex, not as activation of one particular anatomical point.4SpringerLink. The complexity of female orgasm and ejaculation
This framing helps explain why the experience varies so much. The size, position, and sensitivity of the clitourethrovaginal complex differ between individuals, and so does the degree to which stimulation of the front vaginal wall reaches the glands and erectile tissue beneath it. Some people find that firm pressure on the front wall reliably produces a sensation of building fluid, while others feel little from the same type of stimulation.
How Common Is It
Estimates of how many women experience ejaculation or squirting vary widely depending on how the question is asked and who is surveyed. A large Swedish cross-sectional study found that about 58% of participants reported having experienced ejaculation or squirting at some point in their lives, with non-heterosexual women reporting it significantly more often than heterosexual women.5Oxford University Press. Women’s experiences of female ejaculation and/or squirting: a Swedish cross-sectional study Other surveys conducted in different populations have produced lower figures, sometimes in the range of 10 to 40%, but the Swedish study had the advantage of a relatively large sample and direct questions about the experience.
The higher rate among non-heterosexual women is interesting and could reflect several things. It may be that sexual practices more common among women who have sex with women, such as sustained manual stimulation of the front vaginal wall, are more likely to trigger ejaculation. It could also reflect different levels of comfort or familiarity with the experience, or differences in how partners respond to it. The study did not attempt to determine why the gap exists, only that it does.
What seems clear is that ejaculation and squirting are not rare or abnormal. Historically, many people who experienced involuntary fluid release during sex assumed they were accidentally urinating and felt embarrassed. The research, while still evolving, suggests the phenomenon is both common and physiologically normal.
The “Is It Just Pee?” Question
This is probably the most common question people actually want answered, and the honest response is that it depends on which component you are talking about. The glandular ejaculate from Skene’s glands is clearly not urine. Its chemical composition is distinct, and it originates from tissue that is structurally analogous to the prostate. The squirting fluid, however, does originate from the bladder and is chemically similar to very dilute urine, even though it often looks and smells different from what most people recognize as urine.
The ultrasound study that tracked bladder volume during arousal was fairly unambiguous on this point: the bladder was demonstrably empty before stimulation began, filled during arousal, and emptied at the point of squirting.2Wiley Online Library. Nature and origin of “squirting” in female sexuality That said, calling it “just pee” misses important nuance. The fluid is being produced under different physiological conditions than normal urination, it is more dilute, and it is mixed with prostatic secretions in many cases. The involuntary release is also neurologically distinct from the conscious decision to urinate, involving strong pelvic muscle contractions associated with orgasm rather than the normal voiding reflex.
Researchers who have studied male squirting (a separate but related phenomenon) found that color Doppler ultrasound recorded powerful contractions of the prostate and pelvic striated muscles just before fluid was expelled, with the fluid stream moving rapidly from the bladder through the urethra.6Wiley Online Library. Male squirting: Analysis of one case using color Doppler ultrasonography The mechanism appears similar in both sexes: strong pelvic contractions during high arousal or orgasm force fluid from the bladder outward. The fact that the bladder is involved does not mean the event is the same as ordinary urination, any more than tears produced by crying are the same as tears produced by an eye irritant just because both come from the same glands.
Why the Science Is Still Patchy
One of the frustrating things about this topic is how thin the evidence base remains. The ultrasound study that made headlines in 2015 involved seven women. Most biochemical analyses of female ejaculate have been case studies or have examined fluids from fewer than a dozen participants. Even the Swedish prevalence study, which was relatively large by the standards of this field, relied on self-report and could not distinguish between ejaculation and squirting in participants’ responses.
There are practical reasons for this. Studying sexual arousal and orgasm in a lab setting is difficult to fund, difficult to recruit for, and raises ethical-review challenges that studies of, say, knee cartilage do not face. The researchers who do this work tend to have small budgets and rely on volunteer participants who are comfortable with being monitored during sexual activity, which is an inherently self-selected group. The result is that much of what we know comes from small samples that may not represent the broader population.
Anatomical variability adds another layer of difficulty. Skene’s glands differ in size and development from person to person, and some imaging studies suggest that the glands may be larger or more active in women who report regular ejaculation. But establishing causation from that observation would require the kind of large-scale imaging study that simply has not been done. For now, the field is working with suggestive evidence from small studies, and confident claims about exactly how the process works are running ahead of the data.
Variation Between People
Not everyone who has a vulva experiences ejaculation or squirting, and the volume, consistency, and circumstances vary enormously among those who do. Some people produce a barely noticeable amount of moisture that they might not even identify as ejaculation. Others experience a gush large enough to soak through bedding. Both are within the range of normal.
The type of stimulation matters. Ejaculation and squirting are more commonly reported during stimulation of the front vaginal wall, which puts pressure on the clitourethrovaginal complex.4SpringerLink. The complexity of female orgasm and ejaculation But some people report it during clitoral stimulation alone, and others experience it without orgasm at all, during a period of intense arousal that does not reach climax. The relationship between ejaculation and orgasm is not one-to-one: they can occur together, separately, or not at all, depending on the individual and the circumstances.
Hormonal status, hydration levels, pelvic floor muscle tone, and psychological comfort likely all play a role. Anecdotally, many people report that ejaculation became easier or more noticeable after they stopped worrying about it and relaxed their pelvic muscles rather than tensing them. This fits with the physiology: involuntary bladder emptying during orgasm would be suppressed by a tightly clenched pelvic floor and facilitated by relaxation. But controlled research on the role of pelvic floor tension in ejaculation is scarce.
How Pornography Has Shaped Perceptions
The popularity of squirting in mainstream pornography has created a distorted baseline for what the experience looks like. In most pornographic depictions, squirting involves large, forceful streams of clear fluid, which bears little resemblance to what the majority of people experience in real life. Some performers have openly discussed using techniques that essentially trigger bladder emptying on command, which produces visually dramatic results but is not physiologically the same as arousal-driven ejaculation from Skene’s glands.
This has practical consequences. People who expect squirting to look like what they see on screen may feel inadequate when their own experience involves a modest amount of fluid, or they may push themselves to “achieve” something that is largely a performance artifact. Partners may also develop unrealistic expectations, interpreting the absence of a dramatic gush as a sign that stimulation was insufficient. The Swedish study found that most women who had experienced ejaculation or squirting described it as a positive experience, but a subset reported feeling embarrassed or worried that they were urinating.5Oxford University Press. Women’s experiences of female ejaculation and/or squirting: a Swedish cross-sectional study Closing the gap between the cultural image and the physiological reality would likely reduce both the performance pressure and the shame.
Understanding that the fluid is a mix of glandular secretion and dilute bladder contents, that the volume varies hugely, and that many people never experience it at all reframes the event as a normal aspect of sexual physiology rather than a goal to be unlocked or a problem to be solved. The science, limited as it still is, consistently points in that direction.
