Squirting is the involuntary release of fluid from the urethra during sexual arousal or orgasm. It’s a normal physiological response that roughly 58% of women report experiencing at least once, based on a Swedish cross-sectional study of over 1,200 women. Despite how common it is, squirting has been poorly understood for decades, and only recent research has clarified what’s actually happening in the body.
What Happens in the Body
During sexual arousal, the bladder fills with fluid more rapidly than it normally would. Ultrasound studies have confirmed this directly: researchers scanned women before arousal and found completely empty bladders, then scanned again just before squirting and found noticeable bladder filling, then scanned a third time afterward and found the bladder empty again. The fluid is expelled through the urethra, not the vagina, which is why it can come out with force and in relatively large volumes.
The volume varies enormously from person to person and from one experience to the next. Published research documents a range from less than 1 milliliter (barely noticeable) to more than 150 milliliters (enough to soak through sheets). Most squirting events involve 10 milliliters or more of thin, clear or slightly cloudy fluid.
Squirting vs. Female Ejaculation
These two terms get used interchangeably, but researchers now consider them distinct phenomena that can happen separately or at the same time.
- Squirting is the high-volume release of dilute fluid from the bladder through the urethra. The fluid is chemically similar to very dilute urine, though it’s typically clear and less concentrated than normal urine.
- Female ejaculation is the secretion of a small amount of thick, milky fluid from the Skene’s glands (also called the paraurethral glands). This fluid contains prostate-specific antigen, the same protein found in male prostate secretions. The volume is usually just a few milliliters.
In practice, many women experience both at once: a larger gush of dilute fluid mixed with a smaller contribution from the Skene’s glands. This is why biochemical analysis of squirting fluid often finds trace amounts of prostatic proteins alongside markers consistent with urine.
The Role of the Skene’s Glands
The Skene’s glands sit on either side of the urethral opening and develop from the same embryonic tissue that becomes the prostate in males. For this reason, they’re sometimes called the “female prostate.” During arousal, these glands swell with increased blood flow and secrete a mucus-like lubricating fluid. The milky substance they produce contains proteins similar to those in male semen.
Not all women have Skene’s glands of the same size. Some women have prominent glands, others have very small ones, and the size appears to vary naturally across the population. This anatomical variation likely plays a role in why the experience differs so much from person to person.
What Triggers It
Stimulation of the front (anterior) wall of the vagina is the trigger most commonly associated with squirting. This area, sometimes called the G-spot, sits roughly 1 to 5 centimeters inside the vaginal opening along the wall closest to the belly button. It overlaps with the tissue surrounding the urethra and Skene’s glands, which is why pressure there produces a distinctive sensation.
In one study, 72.6% of women who reported a sensitive spot on the anterior vaginal wall also associated it with ejaculation. Researchers have found that the area often feels slightly textured or swollen compared to the surrounding tissue, and it becomes more pronounced during arousal as blood flow increases. Digital (finger) stimulation using a “come hither” motion is the most studied method for activating the area, though vibrators and intercourse positions that angle toward the front vaginal wall can produce the same effect.
It’s worth noting that squirting doesn’t always accompany orgasm. Some women squirt before orgasm, some during, and some without reaching orgasm at all. The release of fluid is a reflexive response to stimulation, not a guaranteed marker that orgasm has occurred.
Why It Feels Like Needing to Urinate
Because squirting involves fluid passing through the urethra from a rapidly filling bladder, the buildup often feels identical to the urge to urinate. This sensation causes many women to tense up or stop stimulation, which can prevent the release. The similarity makes sense anatomically: the same nerve pathways and the same exit route are involved. Understanding that this “need to pee” feeling is part of the process, not a sign that something is going wrong, is one of the most practical things to know about squirting.
Is the Fluid Urine?
This is the most debated question in the research, and the honest answer is: mostly, yes, but not exactly. The 2015 ultrasound study published in the Journal of Sexual Medicine concluded that squirting is “essentially the involuntary emission of urine during sexual activity, although a marginal contribution of prostatic secretions to the emitted fluid often exists.” The bladder fills and empties during the process, and the fluid contains urea and creatinine, both normal components of urine.
However, the fluid is significantly more dilute than typical urine. It’s usually clear or only faintly yellow, often odorless or nearly so, and contains prostatic proteins that urine does not. So while it originates from the bladder and shares some chemical markers with urine, it’s not the same as simply urinating. The body appears to produce a distinctly diluted fluid during arousal that passes through the same plumbing.
How Common It Is
Squirting is far more common than many people assume. In the Swedish study of 1,250 women, 58% reported personal experience with ejaculation or squirting. Some women experience it regularly with certain types of stimulation, while others have experienced it only once or a handful of times. Neither pattern is abnormal.
Women who have never squirted are equally normal. The variation in Skene’s gland size, pelvic floor muscle tone, arousal patterns, and individual anatomy all influence whether it happens. It’s not a skill to master or a benchmark of sexual response. Some bodies do it readily, some do it rarely, and some never do.
