Squirting is the involuntary release of fluid from the urethra during sexual arousal or orgasm. It’s a normal physiological response that roughly 40% of U.S. adult women have experienced at least once in their lifetime, with a typical frequency of three to five times total. Despite how common it is, squirting remains widely misunderstood, partly because it’s often confused with a related but distinct phenomenon called female ejaculation.
Squirting and Female Ejaculation Are Different Things
Most people use “squirting” and “female ejaculation” interchangeably, but researchers now treat them as separate events that can happen independently or at the same time.
Squirting involves a larger volume of fluid, typically 10 milliliters or more, that is clear and watery. This fluid comes from the bladder, and its chemical makeup is similar to diluted urine, though it’s often more diluted than typical urine because it accumulates rapidly during arousal rather than through the normal kidney filtration cycle. Female ejaculation, by contrast, produces just a few milliliters of thicker, milky fluid. This smaller secretion comes from the Skene’s glands, two small structures located on either side of the urethra. The proteins in this fluid actually resemble components found in male semen.
In practice, many women who squirt are releasing a mix of both fluids at once: a larger volume of bladder-derived liquid with a small contribution from the Skene’s glands. That’s why biochemical analyses of squirting fluid often detect traces of prostatic secretions alongside the primary urine-like component.
What Happens in the Body
Ultrasound imaging has given researchers a clear picture of the mechanics. In a study that monitored women’s bladders before, during, and after squirting, all participants started with a completely empty bladder. As sexual arousal built, the bladder filled noticeably, sometimes within minutes. Immediately after squirting, the bladder was empty again. This rapid filling and release is what distinguishes squirting from ordinary urination. The fluid accumulates quickly during arousal and is expelled involuntarily through pelvic muscle contractions during or near orgasm.
The Skene’s glands, sometimes called the female prostate because they develop from the same embryonic tissue as the male prostate, play a supporting role. During arousal, blood flow to the genital area causes these glands to swell. They secrete a small amount of fluid that may mix with the larger bladder output. Outside of sexual activity, the Skene’s glands serve a protective function, producing substances that lubricate the urethral opening and help prevent urinary tract infections.
What Triggers It
Squirting is most commonly associated with stimulation of the front wall of the vagina, the area popularly known as the G-spot. In one study, 72.6% of women who reported having a sensitive G-spot area also reported ejaculation. Among women who could localize a specific sensitive spot on the anterior vaginal wall, 100% reported ejaculation, compared to 24.5% of those who described a more diffuse sensitivity.
The anatomy behind this is worth understanding. The front vaginal wall sits directly against a cluster of structures that researchers call the clitourethrovaginal complex. This includes the internal roots of the clitoris, the urethra, and the Skene’s glands, all packed closely together. When pressure is applied to the front vaginal wall, whether by fingers, a toy, or a partner during penetration, it compresses these structures against the pubic bone. Imaging studies have shown that during penetration, the clitoral roots are stretched and pressed into close contact with the anterior vaginal wall, which likely explains why this area feels particularly sensitive. The stimulation isn’t really hitting one isolated “spot” so much as engaging an interconnected network of erectile and glandular tissue.
That said, squirting doesn’t require any specific type of stimulation. Some women experience it during clitoral stimulation alone, during penetration, or during orgasm from any source. There’s no evidence that clitoral and vaginal orgasms are fundamentally different processes. The distinction between the two is largely a holdover from outdated psychological theories rather than something supported by anatomy.
Is the Fluid Urine?
This is the most common question, and the honest answer is: mostly, yes, but it’s more complicated than that sounds. The fluid originates from the bladder and shares chemical markers with urine. However, it accumulates rapidly during arousal rather than through the standard process of kidney filtration, and it’s typically more diluted than normal urine. Many samples also contain small amounts of prostatic secretions from the Skene’s glands, making the fluid a distinct mixture rather than straightforward urine.
The involuntary nature of squirting also separates it from coital urinary incontinence, which is the unintentional leaking of urine during sex due to pelvic floor weakness. Squirting is tied to arousal and orgasm, involves rapid bladder filling that doesn’t occur outside of sexual stimulation, and is not a sign of a bladder control problem.
Why It Varies Between People
Not every woman squirts, and among those who do, the experience varies widely in volume, frequency, and ease. Part of this comes down to anatomy. The size and development of the Skene’s glands differ significantly from person to person, and some women have very small or even undetectable glands. Pelvic floor muscle strength, the degree of arousal, hydration levels, and the type of stimulation all play roles.
Among women who have squirted, the median lifetime frequency is just three to five times, suggesting that for most people it’s an occasional event rather than a regular part of sex. Some women can learn to experience it more consistently through specific types of stimulation and relaxation of the pelvic floor muscles, while others never experience it regardless of technique. Neither outcome indicates anything about sexual health or function.
