Squirting is the expulsion of fluid from the urethra during sexual arousal or orgasm. The volume can range from a small amount to a significant gush, with studies recording anywhere from 1 to 900 milliliters. It’s a real physiological event, not a performance, and estimates suggest somewhere between 10 and 54 percent of women experience it at some point.
Where the Fluid Comes From
Despite common assumptions, the fluid released during squirting does not come from the vagina. It exits through the urethra, the same opening used for urination. Ultrasound imaging has shown that even when women empty their bladder immediately before sexual stimulation, the bladder rapidly refills during arousal. Scans taken just before climax show a full bladder, and scans taken immediately after squirting show it empty again. This means the bulk of the fluid originates from the bladder.
Chemical analysis of the fluid confirms it contains urea and creatinine, both markers found in urine. But the fluid isn’t purely urine. It also frequently contains prostate-specific antigen (PSA), a protein produced by the Skene’s glands, two small ducts located on either side of the urethra. These glands develop from the same embryonic tissue that becomes the prostate in males, which is why they’re sometimes called the “female prostate.” During arousal, the Skene’s glands swell with increased blood flow and can release a milky secretion containing proteins similar to those found in male semen. So squirting fluid is best understood as a mix: mostly dilute fluid from the bladder, with a smaller contribution from the Skene’s glands.
Squirting vs. Female Ejaculation
Researchers increasingly treat these as two related but distinct events. Female ejaculation refers to a small volume of thick, whitish fluid secreted by the Skene’s glands. It can happen without anyone noticing. Squirting, by contrast, involves a larger, more watery release from the urethra that’s far more visible. Both can occur at the same time, and in practice many women experience a blend of the two. The confusion between them has fueled decades of debate about whether squirting is “just urine,” when the more accurate answer is that it’s a combination with a unique profile.
What Triggers It
Squirting is most commonly linked to stimulation of the G-spot, a sensitive area on the front wall of the vagina roughly 2 to 3 centimeters inside. Clitoral stimulation can also trigger it, and some women experience squirting from a combination of both. It can happen with or without orgasm, meaning the two events are connected but not dependent on each other.
Pelvic floor muscles play a role. The pubococcygeus muscle, which wraps around the vagina and urethra, contracts during orgasm and may contribute to the expulsion of fluid. Women with stronger pelvic floor tone often report more intense orgasmic responses generally, though there’s no evidence that pelvic floor exercises will reliably “cause” squirting for someone who hasn’t experienced it before. The physical mechanism likely involves involuntary muscle contractions creating pressure that pushes fluid through the urethra.
How Common It Is
Population estimates vary widely because the experience is difficult to standardize in research. Broad surveys suggest fewer than half of women ejaculate during sexual stimulation at some point in their lives. Among women who do experience it, most report it happening regularly rather than as a one-time event. One international survey of 320 women who squirt found that about 32 percent did so a few times a week, 28 percent a few times a month, and roughly 19 percent daily. On average, these women reported squirting during about 57 percent of their sexual encounters.
The wide range in prevalence estimates (10 to 54 percent) likely reflects differences in how studies define squirting, how comfortable participants feel reporting it, and whether researchers distinguish between large-volume squirting and smaller-volume ejaculation. Many women may experience mild fluid release without recognizing it as squirting.
Why Volume Varies So Much
The recorded range of 1 to 900 milliliters is enormous, and several factors contribute. Hydration levels directly affect how much fluid the bladder produces during arousal. The duration and type of stimulation matter as well. Some women consistently produce a small amount of fluid, while others experience a large, forceful release. Neither end of the spectrum is abnormal. The variation simply reflects differences in anatomy, arousal patterns, and how the bladder and Skene’s glands respond to stimulation in a given person.
What It Feels Like
Many women describe a sensation of building pressure, similar to the feeling of needing to urinate, just before squirting occurs. This makes sense given the bladder’s involvement. The similarity to the urge to urinate leads some women to tense up or hold back, which can prevent the release. Others describe a sensation of “letting go” that coincides with orgasm or intense pleasure. The experience itself is not painful, and the fluid is generally odorless or has only a very faint scent, distinguishing it from typical urine even though it shares some chemical components.
In the survey of women who squirt, participants overwhelmingly reported that the experience had a positive impact on their sexual lives and their partners’ satisfaction. The concern many women feel about squirting, particularly worry that it’s urine or that something is wrong, tends to diminish once they understand the physiology behind it.
