Squirting is a release of fluid from the urethra during sexual arousal or orgasm, and it happens to somewhere between 10 and 54% of women, depending on the study. If it caught you off guard, that’s completely normal. It’s a physiological response to intense stimulation, not something you did wrong or a sign of a medical problem.
What Actually Happened in Your Body
During sexual arousal, especially with G-spot or clitoral stimulation, your bladder rapidly fills with a diluted fluid. When arousal or orgasm hits a certain intensity, your body expels that fluid through the urethra. This can happen during orgasm, but it can also happen without one. The key triggers seem to be a combination of the type of stimulation, your individual anatomy, pelvic floor muscle strength, and nerve sensitivity.
Your pelvic floor muscles play a direct role. These muscles contract reflexively during orgasm, and stronger pelvic floor muscles produce a more forceful expulsion of fluid. That’s why squirting can feel sudden and powerful, almost like a release of pressure you didn’t know was building.
What the Fluid Is (and Isn’t)
This is the part most people want to know: the fluid is mostly diluted urine, but it’s not simply peeing. Biochemical analysis shows that squirting fluid contains urea, creatinine, and uric acid (the same waste products found in urine) but at lower concentrations, with a substantially lower density than normal urine. It also contains small amounts of secretions from the Skene’s glands, two tiny glands located near the urethral opening.
A study that used dye injected into the bladder before sexual stimulation confirmed the bladder as the source. The discharged fluid came out colored with the dye in every case. So the fluid does come from the bladder, but its composition shifts during arousal, becoming more diluted and mixing with glandular secretions.
There’s actually a separate phenomenon called female ejaculation that often gets lumped together with squirting. Female ejaculation produces a much smaller amount of thick, milky fluid directly from the Skene’s glands. That fluid is chemically different: high in glucose, fructose, and a protein also found in male semen. The two can happen at the same time, which adds to the confusion. But squirting, the larger gush of clear fluid, is primarily coming from the bladder.
Why It Happened Now
If you’ve never squirted before, several things could explain why it happened this time. The angle or type of stimulation matters. G-spot stimulation, which targets the front wall of the vagina a couple of inches inside, is the most commonly reported trigger because the Skene’s glands and surrounding tissue sit right behind that area. Clitoral stimulation can also cause it. A new position, a different partner, a toy, or simply a higher level of arousal than usual can all change the equation.
Your Skene’s glands develop from the same embryonic tissue that becomes the prostate in males. Their size varies significantly from person to person, and some researchers believe this anatomical variation helps explain why some people squirt easily, others rarely, and some never do. It’s not a skill issue or a matter of trying hard enough. It’s partly about the body you happen to have.
Squirting vs. Urinary Leakage
Because the fluid comes from the bladder and exits through the urethra, it’s reasonable to wonder whether what happened was actually incontinence. Urologists recognize this as a legitimate question and consider them two distinct things. Stress urinary incontinence during sex typically happens with physical pressure on the abdomen (like certain positions) and isn’t tied to arousal level. Squirting, by contrast, is linked to high arousal or orgasm and is considered a normal physiological sexual response.
The International Continence Society specifically notes that fluid expulsion during sex can signify a high level of arousal but can also be a sign of urinary incontinence, and that the two require different clinical approaches. If the fluid release only happens during intense arousal or orgasm, it’s almost certainly squirting. If it happens during everyday activities like sneezing, laughing, or exercise, or during sex without much arousal, that’s worth bringing up with a healthcare provider.
What to Expect Going Forward
Squirting isn’t something that necessarily happens every time once it’s happened once. It may become more frequent if the same type of stimulation continues, or it may stay occasional and unpredictable. Some people find that being well-hydrated makes it more likely, while others notice it correlates with where they are in their menstrual cycle. None of this is firmly established in research, but the individual variation is wide.
If the volume of fluid is a practical concern, a towel or waterproof blanket underneath you is the simplest solution. Many people find that the sensation leading up to squirting feels similar to needing to urinate, which can cause you to tense up and hold back. Emptying your bladder before sex can help you relax through that sensation without worrying about it. The fluid will still be produced during arousal, but knowing your bladder was empty beforehand can make the experience less anxiety-inducing while you get used to it.
