Female orgasm involves a coordinated response across the nervous system, muscles, and glands that can produce fluid in several different ways. Some women release a small amount of thick, milky fluid from glands near the urethra. Others experience a larger gush of more diluted fluid, often called squirting. Many women experience orgasm with no noticeable fluid release at all. All of these responses are normal.
What Happens in the Body During Orgasm
Sexual arousal sends blood flowing to the genitals, causing the clitoris, vaginal walls, and surrounding tissues to swell. Nerve endings throughout this area become increasingly sensitive, and rhythmic stimulation builds tension in the pelvic floor muscles. At orgasm, those muscles contract involuntarily in a series of rapid pulses, typically lasting 10 to 30 seconds. These contractions are what create the intense, wave-like sensation most people associate with climax.
At the same time, the brain lights up across dozens of regions. fMRI studies show that orgasm activates the reward system (the same circuitry involved in pleasure from food or music), sensory and motor areas, and deep brainstem structures. The result is a flood of dopamine and oxytocin that produces feelings of euphoria, warmth, and relaxation. This brain-wide activation is why orgasm feels like a full-body experience rather than something localized to one spot.
Ejaculation vs. Squirting
These two terms are often used interchangeably, but they describe different physical processes that can happen separately or at the same time.
Ejaculation refers to a small volume of thick, whitish fluid released from the Skene’s glands, two tiny structures located on either side of the urethral opening. These glands develop from the same embryonic tissue as the prostate in males, and the fluid they produce contains some of the same proteins found in semen, including prostate-specific antigen (PSA). During arousal, the tissue surrounding the Skene’s glands swells with blood flow and begins secreting this fluid. At orgasm, or sometimes just before it, the fluid is expelled. The amount is usually small, sometimes just a few drops, and can go unnoticed.
Squirting involves a larger volume of clear, more watery fluid. Ultrasound research published in The Journal of Sexual Medicine tracked what happens inside the body during squirting episodes. Participants emptied their bladders, and scans confirmed the bladder was empty. During arousal, however, the bladder rapidly refilled. After squirting, scans showed it had emptied again. The fluid does pass through the urethra and contains diluted urine components, but chemical analysis also found PSA in the squirted fluid, suggesting the Skene’s glands contribute to it as well. In other words, squirting fluid is a mix: mostly produced by the kidneys during arousal, with secretions from the Skene’s glands blended in.
How Common These Responses Are
Estimates vary widely depending on how the question is asked. In one survey of 233 women, 54% reported a spurt of fluid at orgasm. A larger mail survey of over 1,100 women found about 40% identified as having experienced ejaculation. A smaller clinical study put the number at under 5%. The wide range likely reflects differences in definitions, awareness, and comfort reporting. Many women may produce small amounts of fluid without realizing it, while others experience dramatic squirting that’s impossible to miss.
Whether or not fluid is released has no bearing on the intensity or “success” of an orgasm. Plenty of women have powerful orgasms with no visible fluid at all.
The Role of Internal Stimulation
You may have heard of the G-spot, a supposedly distinct area on the front wall of the vagina said to trigger especially intense orgasms or ejaculation. The scientific picture is complicated. Some dissection studies have identified a cluster of nerve-rich tissue in that location, while others found no distinct anatomical structure. The most useful way to understand it: the front vaginal wall sits directly against the internal portions of the clitoris and the urethra, with the Skene’s glands nestled nearby. Stimulating this area applies indirect pressure to all of those structures at once.
Ultrasound research has shown that vaginal penetration moves this entire complex of tissue (sometimes called the clitourethrovaginal complex) in ways that external clitoral stimulation does not. This is likely why internal stimulation feels qualitatively different and why some women find it more likely to produce ejaculation. But the clitoris, with its roughly 8,000 nerve endings concentrated in the external tip alone, remains the most reliable path to orgasm for the majority of women regardless of fluid production.
Why It Varies So Much Between People
Skene’s glands vary significantly in size from person to person. Some women have prominent glands with well-developed ducts, while in others they’re barely detectable. This anatomical variation is the most likely explanation for why some women ejaculate easily, others only under specific circumstances, and many never do. Hormonal fluctuations, pelvic floor muscle strength, hydration levels, and the type of stimulation all play a role too.
Arousal level matters more than technique. The Skene’s glands need sustained engorgement with blood to produce fluid, which requires enough time and stimulation to become fully aroused. Rushing to orgasm, or feeling anxious or pressured, can short-circuit this process. Comfort and relaxation aren’t just nice-to-haves; they directly affect the physical mechanics of what the body can do.
