When a girl finishes (reaches orgasm), her body goes through a rapid, intense sequence of involuntary muscle contractions, a flood of hormones, and widespread brain activation that together produce the sensation of climax. The whole event typically involves six to ten rhythmic contractions spaced exactly 0.8 seconds apart, a burst of feel-good brain chemicals, and a gradual cooldown period afterward. Here’s what’s actually happening at each stage.
The Muscle Contractions
The most recognizable physical sign of orgasm is a series of involuntary, rhythmic contractions in the pelvic floor muscles, uterus, and anal sphincter. These contractions pulse at intervals of 0.8 seconds, which is the same timing regardless of gender. Women average six to ten of these contractions per orgasm, compared to four to six in men. That’s part of why female orgasms tend to last slightly longer.
These contractions are what create the waves of pleasure that build and then release. They’re entirely involuntary, meaning you can’t consciously control their timing or intensity. Some women feel them strongly, others more subtly, and both are normal.
What Happens in the Brain
Orgasm isn’t just a pelvic event. It lights up the brain more broadly than almost any other human experience. Brain imaging studies show activation across the reward center, the region responsible for emotional memory, areas that process body awareness and motor control, and parts of the brainstem that regulate automatic functions like heart rate and breathing. The hypothalamus, which controls hormone release, also fires intensely.
One of the more interesting findings is that the brain’s pain-processing areas also activate during orgasm, which helps explain why the line between intense pleasure and mild discomfort can blur at the moment of climax. Some researchers describe orgasm as the brain temporarily losing its normal filtering, creating a full-body sensory experience that’s difficult to replicate any other way.
The Hormone Surge
At the moment of orgasm, the pituitary gland ramps up production of two key hormones: oxytocin and prolactin. Oxytocin is often called the bonding hormone because it promotes feelings of closeness, trust, and emotional attachment. It also plays a direct physical role by triggering contractions in the uterus and vaginal walls.
Prolactin rises during arousal and peaks at orgasm. It’s associated with the feeling of satisfaction and relaxation that follows climax. This hormone is also one reason many people feel sleepy afterward. In the reproductive system, both oxytocin and prolactin help facilitate movement of the uterus and vaginal canal, which may assist with sperm transport, though orgasm is not required for conception.
Fluid Release
Some women release fluid at orgasm, and this is a source of a lot of confusion. There are actually two different phenomena that get lumped together. Female ejaculation involves a small amount of thick, milky fluid produced by the Skene’s glands, two tiny ducts located on either side of the urethra. These glands develop from the same embryonic tissue as the male prostate, and the fluid they produce contains proteins similar to those found in semen.
Squirting, which involves a larger volume of thinner fluid, is a separate process. Not all women experience either one, and neither is a reliable indicator of whether an orgasm occurred. The presence or absence of fluid release is simply a variation in anatomy and response.
Post-Orgasm Sensitivity
Almost immediately after orgasm, the clitoris becomes extremely sensitive. In a study of 174 women, 96% reported post-orgasmic clitoral hypersensitivity, and a similar percentage said further clitoral stimulation felt aversive right after finishing. This parallels the sensitivity men experience on the head of the penis after ejaculation.
This sensitivity is why direct clitoral contact can feel uncomfortable or even painful in the seconds following orgasm. It typically fades within a minute or two, though the timeline varies. If you experience sharp or burning pain during or after orgasm that lasts up to an hour, especially in the abdomen or pelvis, that could indicate an underlying condition like ovarian cysts, endometriosis, or pelvic floor dysfunction rather than normal sensitivity.
The Cooldown Phase
After orgasm, the body enters what’s called the resolution phase. Blood that rushed to the genitals, nipples, and skin during arousal gradually drains back to normal circulation. Swollen tissues return to their usual size. Heart rate and breathing slow down. Many women feel a deep sense of relaxation and fatigue as prolactin levels remain elevated.
Some women experience a brief dip in mood after finishing, a phenomenon called postcoital dysphoria. It can involve feelings of sadness, irritability, or anxiety despite the sex itself being positive. The exact cause isn’t fully understood, but hormonal fluctuations during the rapid cooldown likely play a role. Women who have experienced postnatal depression may be more susceptible, possibly due to higher sensitivity to shifting estrogen levels.
Why Multiple Orgasms Are Possible
One major difference between male and female sexual response is the refractory period. After men ejaculate, they enter a mandatory recovery window during which another orgasm is physically impossible. Research suggests that women either don’t have a comparable refractory period or have one that’s significantly shorter and less pronounced.
That said, it’s not as simple as “women can always have multiple orgasms.” The 96% of women who experience clitoral hypersensitivity after finishing often find continued stimulation unpleasant, which creates a practical barrier even if a physiological one doesn’t exist. The key difference is that if stimulation shifts to less sensitive areas or pauses briefly, arousal can rebuild without the body needing to fully reset. Whether this actually happens depends on the individual, the type of stimulation, and the context. Multiple orgasms are a possibility, not a default.
