Squirting is the release of fluid from the urethra during sexual arousal or orgasm. It’s a normal physiological response that surveys suggest around 40 to 58 percent of women have experienced at least one time. Despite its portrayal in pornography as rare or extreme, squirting is a well-documented bodily function with a straightforward biological explanation.
Squirting and Ejaculation Are Two Different Things
One of the biggest sources of confusion is that “squirting” and “female ejaculation” are often used interchangeably, but researchers now consider them related yet distinct phenomena. Squirting involves a larger volume of fluid, typically 10 milliliters or more, that is dilute and mostly clear. Female ejaculation, by contrast, produces just a few milliliters of thicker, milky fluid. Both can happen during the same sexual experience, and some people experience one without the other.
The fluid released during squirting comes primarily from the bladder and passes through the urethra. Its chemical makeup is similar to very dilute urine, containing urea, creatinine, and uric acid. However, in a study that analyzed samples from seven women, five of them also had a protein called PSA (prostate-specific antigen) present in their squirting fluid, which is not typically found in regular urine. This suggests the fluid picks up secretions from nearby glands on its way out.
Female ejaculation fluid, on the other hand, originates from two small glands called the Skene’s glands, located on either side of the urethral opening. These glands are about the size of a small blueberry and develop from the same embryonic tissue that becomes the prostate in males. The fluid they produce contains proteins similar to those found in semen, which is why the Skene’s glands are sometimes called the “female prostate.”
What Triggers It
Squirting is most commonly associated with stimulation of the area on the front vaginal wall sometimes called the G-spot. This isn’t a single anatomical button but rather a zone where several sensitive structures overlap: the internal portions of the clitoris, the Skene’s glands, the urethra, and surrounding tissue that swells with blood flow during arousal. Firm, rhythmic pressure on this area during manual stimulation, intercourse, or with a toy is what most people describe as the trigger.
Research on this area has shown that gentle pressure there can raise pain thresholds by about 40 percent, and during orgasm, tolerance can increase by up to 100 percent. This helps explain why the sensation right before squirting can feel intensely pleasurable rather than uncomfortable, even though the stimulation itself is relatively firm. The buildup of pressure in the surrounding tissue, combined with the rhythmic contraction of pelvic muscles during orgasm, is what expels the fluid through the urethra.
Not everyone who receives this type of stimulation will squirt. The size of the Skene’s glands varies considerably from person to person, and some people have very small or even absent glands. This natural anatomical variation likely explains why some women experience it easily and others never do, regardless of technique.
How Common It Actually Is
Squirting is far more common than most people assume. A large US-based study found that 41 percent of women reported having experienced it. A Swedish cross-sectional study put the number at 58 percent among its participants, with significantly higher rates among non-heterosexual women. Studies from Canada and Egypt have produced similar figures. The consistency across different populations suggests this is a routine part of sexual response for a large portion of women, not an unusual event.
Many people who do experience squirting report that it doesn’t happen every time they have sex or orgasm. It tends to be more likely with specific types of stimulation, higher levels of arousal, and when the person feels relaxed enough not to clench against the sensation of needing to release fluid. That last point matters because the feeling right before squirting closely resembles the urge to urinate, which leads many people to tense up and suppress it.
The “Is It Just Urine?” Question
This is the question most people actually want answered, and the honest answer is: it’s complicated. The squirting fluid does come from the bladder, and it does contain some of the same chemical markers as urine. Ultrasound studies have confirmed that the bladder fills rapidly during arousal and empties during squirting, even if the person urinated immediately beforehand.
But the fluid isn’t identical to regular urine. It’s typically much more dilute, often clear and odorless, and in most women tested, it contains PSA from the Skene’s glands, something ordinary urine does not. Researchers describe it as a modified, highly diluted form of urine mixed with prostatic secretions. Female ejaculation fluid (the smaller, thicker emission from the Skene’s glands) is chemically distinct from urine, with different concentrations of urea and creatinine and a higher proportion of PSA.
So calling squirting “just peeing” oversimplifies the biology. The fluid originates in the bladder, but its rapid production during arousal, its altered composition, and the involvement of the Skene’s glands make it a distinct sexual response rather than simple urinary incontinence. That said, stress urinary incontinence during sex is also a real and separate condition. The difference is that squirting is tied to orgasm and arousal, while incontinence typically occurs with physical pressure or exertion and isn’t pleasure-related.
What It Feels Like
People who squirt describe a range of sensations. The most common is a building feeling of pressure, similar to needing to urinate, that intensifies with continued stimulation. Letting go of that pressure, rather than fighting it, is what most people describe as the moment of release. Some experience it alongside a powerful orgasm, while others say it can happen with or without orgasm.
The volume varies widely. Some people produce a small gush that barely wets the sheets, while others release enough fluid to soak through bedding. Neither end of that spectrum is abnormal. The amount can also change from one experience to the next depending on hydration, arousal level, and the type of stimulation involved.
Squirting is neither a goal to chase nor something to worry about. It doesn’t indicate better sex or stronger orgasms, and its absence doesn’t indicate a problem. It’s one of many possible physical responses during sexual arousal, shaped by individual anatomy, comfort, and circumstance.
