The white, creamy fluid that appears during sex is produced by a combination of vaginal lubrication and secretions from small glands near the urethra. It’s a normal physical response to sexual arousal, and the amount, consistency, and timing vary widely from person to person. Understanding where it comes from helps clarify why it happens more intensely in some situations than others.
Where the Fluid Comes From
There are two distinct sources working at once. The first is vaginal lubrication, which starts as a direct response to arousal. Increased blood flow to the genital area pushes fluid through the walls of the vagina. This fluid is typically clear and slippery, and its job is straightforward: reducing friction during penetration.
The second source is a pair of tiny ducts called the Skene’s glands, located on either side of the urethra. The tissue surrounding these glands swells during sexual stimulation, and they secrete a thicker, milky fluid. This is the fluid most responsible for the white, creamy appearance. It contains proteins similar to those found in semen (minus the sperm), including prostate-specific antigen, or PSA, a marker that confirms it originates from glandular tissue rather than the bladder or vaginal walls.
When vaginal lubrication mixes with Skene’s gland secretions and the natural bacteria that maintain vaginal pH, the result is the opaque, whitish fluid that collects visibly during sex. The ratio of these fluids shifts depending on how aroused you are, where you are in your menstrual cycle, and how long stimulation has been happening.
Arousal Intensity Is the Biggest Factor
The more aroused a person becomes, the more fluid both systems produce. Vaginal lubrication increases steadily with blood flow to the area, and the Skene’s glands respond to prolonged or intense stimulation by releasing more of their thicker secretion. Extended foreplay, positions that create consistent pressure on the front vaginal wall (near where the Skene’s glands sit), and higher levels of mental arousal all contribute to more visible fluid production.
This is why the same person can produce noticeably different amounts of fluid from one encounter to the next. Stress, dehydration, certain medications, and hormonal fluctuations throughout the menstrual cycle all affect how much lubrication the body generates. Around ovulation, cervical mucus also becomes more abundant and stretchy, adding to the overall volume.
Creaming vs. Squirting vs. Ejaculation
These terms get used interchangeably, but they describe different things. “Creaming” typically refers to the thick, white buildup that appears on a partner or toy during penetration. This is the mix of vaginal lubrication and Skene’s gland fluid described above, and it happens gradually as arousal builds.
Female ejaculation is a smaller release of thick, whitish fluid from the Skene’s glands, usually at or near orgasm. Squirting involves a larger volume of thinner, more diluted fluid that contains urea and creatinine (components also found in urine), suggesting it passes through the bladder. The Skene’s glands still contribute PSA to this fluid, so it’s not simply urine, but it’s chemically distinct from the thicker ejaculate.
Some women experience one, two, or all three of these responses. Some experience none. Studies put the prevalence of female ejaculation anywhere from about 5% to 54% of women, depending on how the question is asked and how ejaculation is defined. A large survey of over 1,100 women found roughly 40% reported a noticeable expulsion of fluid at orgasm.
What It Feels Like
For many women, the sensation that accompanies creaming or ejaculation isn’t dramatically different from any other orgasm. Some describe a building warmth and trembling sensation between the thighs as fluid release approaches. Others don’t notice it happening at all until they see it afterward. The intensity of the orgasm itself doesn’t always correlate with the amount of fluid produced. Arousal level and the type of stimulation, particularly pressure or rhythm, play a larger role in how much fluid appears than the strength of the orgasm.
Why It Varies So Much Between People
Skene’s glands vary significantly in size from person to person. In some women, they’re large enough to be detected on imaging; in others, they’re nearly vestigial. This anatomical difference alone explains why some women consistently produce visible creamy fluid during sex while others rarely do, regardless of how aroused they are.
Hydration matters too. The body needs adequate water intake to produce both vaginal lubrication and glandular secretions. Hormonal birth control can reduce lubrication in some women by lowering estrogen levels, which directly affects how much fluid the vaginal walls produce. Perimenopause and menopause have a similar drying effect. None of this reflects arousal level or sexual response. It’s purely mechanical: the glands and tissues need the right hormonal and hydration conditions to function at full capacity.
Comfort and relaxation also play a role that’s easy to underestimate. Tension in the pelvic floor muscles can restrict blood flow to the area and reduce the body’s lubrication response. Being mentally present, feeling safe, and not rushing through arousal all create conditions where the body’s fluid production systems work more effectively.
