Is squirt pee, an honest answer from the research

The short answer and why it matters

If you have searched this question, you are in very good company. It is one of the most common worries people have the first time they squirt, or the first time a partner does. The honest answer is that squirting fluid is mostly urine from the bladder, in a diluted form, with a small contribution from the Skene's glands.

That answer can feel deflating, but it should not. Knowing where the fluid comes from does not change the fact that squirting happens during arousal, often feels good, and is a normal part of some people's sexual response. It also means there is nothing mysterious or dangerous going on.

What the key study found

The best known study on this question is by Samuel Salama and colleagues, published in the Journal of Sexual Medicine in 2015. It was small, with only a handful of women who reported regularly releasing large amounts of fluid during sex. Here is what the researchers did, step by step.

1. The women emptied their bladders, and a pelvic ultrasound confirmed the bladder was empty.
2. They were sexually stimulated until just before squirting, and a second ultrasound was taken.
3. After squirting, a third ultrasound was taken.

The second scan showed the bladder had filled noticeably again during arousal. The third scan, right after squirting, showed it was empty once more. That points clearly to the bladder as the main source of the fluid.

The researchers also tested the fluid. It contained urea, creatinine and uric acid, the usual chemical markers of urine. In most samples they also found PSA (prostate specific antigen), which was absent from the urine collected before arousal. That PSA most likely came from the Skene's glands.

Why it is not the same as ordinary pee

"Mostly urine" is accurate, but "just pee" misses some things.

• It is usually very diluted. Many people describe squirting fluid as clear, watery and with little or no smell, unlike the yellow urine of the morning.
• It often contains gland fluid. The PSA found by Salama and colleagues shows that a little Skene's secretion usually mixes in.
• It happens in a different context. It shows up during strong arousal and specific stimulation, not because of a full bladder pressing to be emptied.

The bladder fills quite quickly during arousal in some people, and the release is linked to sexual stimulation and the muscles of the pelvic floor. Researchers still do not fully understand the mechanism, and studies have been small. Experiences vary a great deal from person to person.

Squirting vs female ejaculation

Much of the confusion comes from mixing up two different things. In his 2013 review, Zlatko Pastor described squirting and female ejaculation as separate phenomena, and Rubio-Casillas and Jannini had made a similar point in 2011.

Female ejaculation is a small amount of thick, whitish fluid from the Skene's glands. It is not urine. Squirting is the larger gush of clear fluid, mostly from the bladder. Some people do one, some do both, many do neither. Our guide to female ejaculation covers the gland fluid in more detail.

Is it incontinence

No, not in the medical sense, and the difference matters. Urinary incontinence means leaking urine when you do not intend to, such as during coughing, laughing, running or with a sudden urge. That is a pelvic floor or bladder problem that deserves care.

Squirting happens during sexual arousal, often with a building sense of fullness and then release. Many people feel it as a pleasurable part of sex. There is a related condition called coital incontinence, where urine leaks during sex in a way the person does not want or enjoy. If that describes you, it is worth talking to a professional rather than calling it squirting. Our page on whether you squirted or peed helps you tell these situations apart.

Practical tips if the idea bothers you

Some people simply feel more relaxed knowing a few practical things.

• Empty your bladder first. Many people pee before sex. This does not always stop squirting, since the bladder can refill during arousal, but it can reduce the volume and ease the worry.
• Protect the bed. A towel or a waterproof sex blanket means you do not need to think about the sheets.
• Talk about it. Partners who know what to expect tend to relax, and relaxation usually makes sex better for everyone.
• Drop the idea that it must happen. Squirting is not a goal or a measure of good sex.

What partners should know

If your partner squirts, how you react shapes how relaxed they feel next time. A calm, warm response helps far more than surprise or jokes. Remember that the fluid is harmless, that it is a known sexual response, and that it says nothing negative about hygiene or health.

It also helps to agree on a few practical things beforehand, such as having a towel within reach and checking in during sex about what feels good. If your partner prefers not to squirt, respect that and change the kind of stimulation. If they enjoy it, there is no need to chase it every time. Consent and comfort come first, always.

Some partners worry that squirting means they did something wrong, or that it means they did something especially right. Neither is true. It depends on many factors, most of them in the body of the person squirting, and it can change from one day to the next. The most useful thing a partner can bring is patience.

When to talk to a doctor

See a gynecologist, urologist or pelvic floor physiotherapist if you leak urine outside of sex, if leaking during sex feels unwanted or distressing, if passing urine burns or hurts, or if you notice blood, strong smell or pelvic pain. These are common issues and treatment often helps a lot.
