Female squirting is a rapid release of fluid from the urethra during sexual arousal or orgasm. The volume can range from about half an ounce to three ounces, and it typically happens as a noticeable gush. Though it has been a source of confusion and even embarrassment for some, squirting is a real physiological response with identifiable anatomical origins.
Squirting vs. Female Ejaculation
These two terms are often used interchangeably, but they describe different things. Female ejaculation is a small release of thick, whitish fluid, usually less than a quarter teaspoon. It comes from the Skene’s glands, two small structures located near the lower end of the urethra. These glands develop from the same embryonic tissue that becomes the prostate in males, and the fluid they produce even contains prostate-specific antigen (PSA), the same marker found in male ejaculate.
Squirting, by contrast, involves a much larger volume of fluid and comes out as a rapid gush. Chemically, it’s a mix: some components resemble dilute urine, while others match the fluid produced by the Skene’s glands, including PSA. The two often happen at the same time, which is part of why they get lumped together. But squirting is its own distinct event, different in both volume and composition from the smaller ejaculatory release.
Neither squirting nor female ejaculation is the same as urinary incontinence during sex, though many people worry about that. The fluid released during squirting can contain diluted urinary components, but it also contains glandular secretions that pure urine does not.
Where the Fluid Comes From
The Skene’s glands play a central role. During sexual arousal, increased blood flow causes the tissue surrounding these glands to swell. They secrete fluid that serves multiple purposes outside of sex as well: lubricating the urethral opening during urination and producing antimicrobial substances that help prevent urinary tract infections. During orgasm, these glands can release a mucus-like substance similar in protein composition to components found in semen.
For squirting specifically, the bladder also appears to be involved. In a study from Okayama University, researchers inserted a catheter into the bladders of five women who could reliably squirt, emptied their bladders completely, then injected a blue dye. This helped confirm that the bladder fills rapidly during arousal and contributes fluid to the squirting response. The expelled fluid, however, is not simply stored urine. It’s chemically distinct, containing glandular markers alongside diluted urinary components.
How Common It Is
Estimates vary widely depending on how the question is asked. In one population-based survey of 233 women, 54% reported a spurt of fluid at orgasm. A separate mail survey of 1,172 women found that about 40% identified as having experienced ejaculation. On the lower end, one study of 300 women put the number at just under 5%. The huge range reflects differences in definitions, comfort levels with reporting, and whether researchers distinguish between the small ejaculatory release and the larger squirting response.
When women who could squirt were asked to estimate how common they thought the experience was in the general population, the most frequent guess was around 10%. The actual number likely falls somewhere in the middle of these estimates, with many women experiencing some degree of fluid release without necessarily recognizing or labeling it.
What Triggers Squirting
Stimulation of the front wall of the vagina is the most commonly reported trigger. This area sits close to the Skene’s glands and the internal portions of the clitoris, forming what researchers call the clitorourethrovaginal complex. Ultrasound imaging has shown that vaginal stimulation produces specific movements in this complex that are distinct from what happens during external clitoral stimulation alone. The two types of stimulation appear to activate different physiological pathways.
The response is governed by the parasympathetic nervous system, the branch responsible for “rest and digest” functions as well as sexual arousal. This is the same system that controls erection and lubrication. Relaxation, both physical and mental, plays a significant role. Many women who squirt report that it happens more easily when they feel comfortable, unhurried, and not anxious about the outcome.
Why Some People Experience It and Others Don’t
The Skene’s glands vary significantly in size from person to person. Some are large enough to be visible on imaging, while in others they are barely detectable. This natural anatomical variation likely explains much of the difference in who squirts and who doesn’t. Women with more developed Skene’s glands may simply produce more fluid in response to arousal.
There is no evidence that squirting indicates a “better” orgasm or higher level of arousal. It is one of many possible physiological responses during sex. Some women experience it regularly, some only occasionally, and some never do. None of these patterns is abnormal or a sign of dysfunction.
The Emotional Side
For many women, the first experience of squirting is confusing. The worry that it might be urine is extremely common and can cause significant anxiety or even avoidance of sexual activity. Understanding the anatomy behind it tends to help. Surveys of women who squirt have found that the experience generally has a positive impact on both their own sexual satisfaction and their partners’. Once the concern about incontinence is addressed, most women describe squirting as pleasurable or at least neutral.
If you experience unexpected fluid release during sex and it bothers you, knowing the difference between squirting and urinary incontinence is useful. Squirting typically happens during high arousal or orgasm, involves fluid that may look and smell different from urine, and is associated with sexual stimulation of the front vaginal wall. Stress incontinence, by contrast, tends to happen with physical pressure (coughing, sneezing, or certain positions) and involves pure urine. The two can coexist, but they are separate phenomena with different causes.
