Squirting is the involuntary release of fluid through the urethra during sexual activity. It can happen before, during, or after orgasm, and the volume ranges from a small amount to over 100 milliliters. Around 40% of adult women in the U.S. report having experienced it at least once, with a typical lifetime frequency of three to five times. It’s a normal physiological response, not a sign of anything wrong.
What Actually Happens in the Body
During intense sexual arousal, the bladder can fill rapidly. Ultrasound studies have confirmed this: women whose bladders were empty before arousal showed noticeable bladder filling during stimulation, followed by emptying at the moment of squirting. The fluid exits through the urethra, the same opening urine passes through, which is why it can feel similar to the sensation of needing to pee.
The type of stimulation most commonly linked to squirting involves the front wall of the vagina. This area sits close to a cluster of sensitive tissue sometimes called the G-spot, though researchers now describe it more accurately as a complex that includes the internal portions of the clitoris, the urethra, and the vaginal wall working together. Stimulating this area, especially combined with clitoral stimulation or oral sex, tends to produce more intense orgasms and is more likely to trigger the squirting response.
What the Fluid Is Made Of
This is the part that surprises most people. Biochemical analysis shows the fluid is primarily dilute urine. It contains urea, creatinine, and uric acid at concentrations comparable to what’s found in the bladder. A 2015 study that tracked bladder volume with ultrasound and analyzed the fluid confirmed that it comes from the bladder and is, at its core, an involuntary emission of urine during sexual activity.
But it’s not purely urine. In five out of seven women in that same study, the squirting fluid also contained prostate-specific antigen (PSA), a protein produced by small glands called the Skene’s glands. These glands sit on either side of the urethral opening and function as a kind of female prostate. They produce a mucus-like secretion during arousal that mixes into the fluid as it passes through the urethra. So the composition is mostly bladder fluid with a small contribution from these glands.
Squirting vs. Female Ejaculation
These two terms get used interchangeably, but researchers now consider them distinct events that can happen separately or at the same time.
- Squirting involves 10 milliliters or more of clear, watery fluid that comes from the bladder. It’s the larger, more visible release most people picture.
- Female ejaculation is a much smaller secretion, just a few milliliters of thick, whitish fluid that comes from the Skene’s glands. It contains a high concentration of PSA and has chemical markers similar to some components of male semen.
Many women experience both simultaneously, which is why the squirting fluid often tests positive for PSA even though most of it originates in the bladder. The ejaculate from the Skene’s glands gets carried along with the larger volume of fluid. Because the two events overlap so frequently, telling them apart without lab analysis is essentially impossible in real life.
What It Feels Like
The most commonly reported sensation right before squirting is pressure, often described as feeling like you need to urinate. This makes sense given the rapid bladder filling that happens during arousal. Many women say the key difference between squirting and simply having an orgasm is a moment of “letting go” rather than tensing up. Holding back against that pressure tends to prevent it from happening.
The release itself typically coincides with orgasm, though not always. Some women squirt without orgasming, and many orgasm without squirting. The two are related but not the same thing. Women who do experience both together often describe the combined sensation as a more intense or full-body orgasm compared to orgasms without squirting.
Why Some Women Squirt and Others Don’t
There’s no clear answer yet on why squirting happens for some women and not others. Skene’s glands vary significantly in size from person to person, and some women appear to have very small or nearly absent glands. This likely influences whether the ejaculatory component is present, though it may not fully explain the bladder-emptying aspect.
Arousal intensity, the type of stimulation, comfort level with a partner, and pelvic floor muscle strength all seem to play a role. The 40% prevalence figure suggests it’s common but far from universal. Women who have never experienced it aren’t missing out on some required sexual milestone, and women who do experience it aren’t doing anything unusual. It’s simply one of many ways the body can respond to sexual stimulation.
Practical Considerations
Because the fluid is mostly dilute urine, it’s worth knowing that it can be more than a few drops. Laying down a towel or using a waterproof mattress protector takes care of the cleanup concern that bothers most people. The fluid is generally clear or very pale and has little to no odor, especially when someone is well hydrated.
If squirting happens and you weren’t expecting it, there’s nothing to worry about medically. If it bothers you, emptying your bladder before sex can reduce the volume. If you’re curious about experiencing it, stimulation of the front vaginal wall combined with clitoral stimulation is the approach most commonly associated with triggering the response, though relaxing into the sensation of pressure rather than fighting it matters just as much as technique.
