Squirting happens when fluid is expelled from the urethra during sexual arousal or orgasm, typically in response to stimulation of the sensitive area along the front vaginal wall. It’s a normal physiological response that somewhere between 10 and 54 percent of women experience, depending on which survey you look at. The wide range reflects how differently women define and recognize the experience, but the biology behind it is increasingly well understood.
Two Different Fluids, Two Different Sources
One of the most important findings in recent research is that “squirting” and “female ejaculation” are technically two separate things, even though most people use the terms interchangeably. They involve different fluids coming from different sources, and they can happen independently or at the same time.
Female ejaculation, in the strict scientific sense, refers to a small amount of thick, milky white fluid released during orgasm. This fluid comes from the Skene’s glands, two small structures 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.” The fluid they produce contains proteins similar to those found in male semen, including PSA (the same protein measured in prostate cancer screenings) along with fructose and other compounds.
Squirting, on the other hand, involves a much larger volume of clear, watery fluid. Biochemical analysis shows this fluid is chemically similar to diluted urine. It contains urea, creatinine, and uric acid, all markers found in urine, but at lower concentrations than normal urine. It also contains small amounts of PSA from the Skene’s glands, which confirms it picks up secretions from the female prostate on its way out. So while squirting fluid originates primarily from the bladder, it isn’t simply urine. It’s a distinct mix that forms during arousal.
Where the Fluid Comes From
The Skene’s glands sit within a complex zone of tissue surrounding the urethra. This area includes the internal structure of the clitoris, the urethra itself, and the glandular tissue of the female prostate. During sexual arousal, blood flow increases to this entire region, causing the tissues to swell. The Skene’s glands respond by producing and releasing their secretions.
For the larger-volume squirting fluid, the bladder appears to play a direct role. Ultrasound studies have shown that the bladder fills rapidly during arousal, even in women who emptied it immediately beforehand, and then empties again at the moment of squirting. The kidneys seem to produce fluid at an accelerated rate during intense stimulation, and the resulting liquid mixes with prostatic secretions before being expelled through the urethra.
What Triggers It
Squirting is most commonly associated with stimulation of the area along the front wall of the vagina, roughly 2 to 3 centimeters inside. This region, often called the G-spot, isn’t a single anatomical structure. It’s a zone where the vaginal wall sits close to the internal portions of the clitoris, the urethra, and the Skene’s glands. Pressure on this area stimulates all of these structures simultaneously, which is why it can feel distinctly different from other types of stimulation.
Not every woman who receives this type of stimulation will squirt, and some women squirt from clitoral stimulation alone or from other forms of arousal. The experience varies widely. Some women squirt every time they orgasm, others only occasionally, and many never do. Part of this variation likely comes down to anatomy. The size and development of the Skene’s glands differ significantly from person to person. Some women have prominent glandular tissue, while in others it’s minimal or nearly absent. Women with more developed Skene’s glands may be more likely to produce noticeable fluid.
Psychological factors also play a role. Tension in the pelvic floor muscles, the level of relaxation during arousal, and comfort with the sensation all influence whether fluid is released. Many women describe an initial feeling similar to needing to urinate, which can lead to involuntarily holding back. Relaxing through that sensation is often what allows squirting to happen.
How Common It Actually Is
Estimates vary dramatically depending on how the question is asked. In one population survey of 233 women, 54 percent reported a spurt of fluid at orgasm. A larger mail survey of over 1,100 women found that about 40 percent identified as having experienced ejaculation. Other studies put the number much lower, with one finding only about 5 percent of 300 women reported the experience. The inconsistency reflects real differences in how women perceive and categorize what’s happening. A small amount of fluid during orgasm might go unnoticed, while a larger gush is hard to miss.
The volume of fluid also varies enormously. Female ejaculate from the Skene’s glands alone might be just a few drops. Squirting fluid can range from a teaspoon to enough to soak through bedding. Both are normal, and neither indicates anything about arousal level, orgasm quality, or sexual health.
Why Some Women Squirt and Others Don’t
The biggest factor appears to be anatomical variation in the Skene’s glands themselves. These glands don’t develop to the same size or complexity in every woman. Autopsy and imaging studies have found that some women have well-developed glandular tissue with multiple ducts opening into the urethra, while others have very little. This isn’t something you can change, and it doesn’t reflect sexual function or responsiveness.
Pelvic floor strength may also contribute. The muscles surrounding the vagina and urethra contract during orgasm, and stronger contractions could help expel fluid that’s accumulated in the Skene’s glands or urethra. Some women report that squirting became more frequent after they began doing pelvic floor exercises, though this hasn’t been studied in a controlled way.
The type and intensity of stimulation matters too. Internal pressure on the front vaginal wall creates direct mechanical contact with the Skene’s glands and surrounding erectile tissue. Sustained, rhythmic stimulation of this area during high arousal is the pattern most commonly associated with squirting. But bodies differ, and what works is highly individual.
