It is a sudden, intense peak of sexual pleasure. For some, it feels like a total mental blackout. For others, it’s a rhythmic pulse that starts deep in the pelvis and radiates outward until their toes curl. But if you strip away the poetry and the romance, what happens during female orgasm is actually a complex, high-speed coordination of the nervous system, blood flow, and muscle contractions. It isn't just "in the head," though the brain is definitely the conductor of this particular orchestra.
Most people think of it as a single event. It’s not. It is a process.
The Four Stages of the Human Sexual Response
To understand the "big moment," we have to look at the work of William Masters and Virginia Johnson. Back in the 1960s, they mapped out what they called the Human Sexual Response Cycle. While their work has been updated by researchers like Rosemary Basson—who argues that female desire is often more circular and emotional than linear—the physical stages they identified still hold up under a microscope.
First, there is excitement. Your heart rate climbs. Blood starts rushing to the pelvic region in a process called vasocongestion. This isn't just about lubrication; the tissues of the clitoris, which is much larger than most people realize, actually engorge and become firm. The clitoris is essentially the only organ in the human body dedicated entirely to pleasure, boasting over 10,000 nerve endings.
Then comes the plateau. This is the tension-building phase. The outer third of the vagina swells, creating what researchers call the "orgasmic platform." The uterus may actually shift position, pulling upward in a "tenting" effect. You’re breathing faster now. Your skin might even get a "sex flush," which is a temporary rash caused by increased blood flow near the surface. Honestly, it's a full-body workout before the main event even starts.
The Big Bang: What Happens During Female Orgasm
When the body reaches its limit of tension, the nervous system takes over. This is the orgasmic phase.
The brain sends a frantic signal to the pelvic muscles. Specifically, the pubococcygeus (PC) muscles start to contract rhythmically. These contractions usually happen at intervals of about 0.8 seconds. In a mild orgasm, you might feel three or four of these pulses. In an intense one? You could be looking at ten to fifteen.
But it’s not just the vagina. The uterus and the anal sphincter also contract in unison. It’s a total pelvic "reset."

Meanwhile, your brain is essentially on fire. Using fMRI scans, researchers like Dr. Barry Komisaruk at Rutgers University have shown that during the peak, over 30 different areas of the brain light up. This includes the prefrontal cortex—the part responsible for logic and self-control—which basically shuts down. This "quieting" of the brain is why many women report a feeling of transcendence or a loss of self-consciousness. You aren't thinking about your grocery list anymore. You can’t.
The Chemical Cocktail
Once the physical pulsing stops, your brain floods the system with a massive dose of neurochemicals. This is why you feel that "afterglow."
- Oxytocin: Often called the "cuddle hormone," it creates a sense of bonding and emotional closeness.
- Dopamine: The reward chemical. This is what makes the experience feel addictive and intensely pleasurable.
- Prolactin: This is the "satiety" hormone. It’s what tells your body, "Okay, we’re done now." It’s also largely responsible for the refractory period, though women generally have a much shorter or even non-existent refractory period compared to men, allowing for multiple orgasms.
- Endorphins: These are the body's natural painkillers. They induce a state of relaxation and euphoria.
The Clitoral vs. Vaginal Debate
For decades, there was a weirdly clinical obsession with "types" of orgasms. Freud famously (and incorrectly) claimed that vaginal orgasms were "mature" and clitoral ones were "immature." Modern science has pretty much debunked that nonsense.
The clitoris is a powerhouse. It has two "roots" or crura that wrap around the vaginal opening and bulbs that extend deep into the pelvic floor. When you have what feels like a vaginal orgasm, you are likely stimulating the internal structures of the clitoris through the vaginal wall. It’s all connected. The "G-spot" isn't necessarily a separate button; it’s more like a sensitive zone where the vaginal wall meets the internal clitoral structure and the Skene’s glands.
Some women prefer external stimulation. Some prefer internal. Some need both. All of it results in the same physiological climax: the rhythmic muscle contractions and the dopamine dump.
Why It Doesn't Always Happen
Let's be real: the "orgasm gap" is a documented phenomenon. In heterosexual encounters, women reach orgasm significantly less often than men. Why? Usually, it's a lack of targeted stimulation.
Studies published in the Archives of Sexual Behavior suggest that about 75% of women require clitoral stimulation to reach orgasm. If a sexual encounter focuses solely on penetration, many women simply won't hit that threshold of tension required to trigger the reflex. It's not a "dysfunction." It’s just biology. Stress is another massive killer. Since the orgasm requires the nervous system to switch from "alert" to "release," high levels of cortisol (the stress hormone) can act like a brick wall.
Physical Aftermath and Resolution
The final stage is resolution. This is when the blood leaves the pelvic tissues and returns to the rest of the body. The clitoris might become hypersensitive—sometimes even painfully so—to further touch. This is because the nerve endings are still firing at a high rate even though the peak has passed.
Muscle tension relaxes. The heart rate slows down. You might feel sleepy or suddenly very hungry. This is the body’s way of returning to homeostasis after a massive hit to the sympathetic nervous system.
Actionable Insights for Better Results
Prioritize the "Plateau" Phase
Don't rush the process. The longer the plateau phase lasts, the more blood pools in the pelvic tissues, which generally leads to a more intense muscular contraction during the climax. Think of it like stretching a rubber band; the further you pull it back, the harder it snaps.
Focus on the Clitoral Hood
Since the clitoris is the primary engine of the female orgasm, focus on it. However, direct stimulation of the glans (the "head") can sometimes be too much. Many find that stimulating the area around it or through the hood provides a more sustainable build-up.
Breath and Pelvic Floor Awareness
Because the orgasm is a muscular reflex, keeping the pelvic floor muscles (the Kegels) healthy can actually increase the intensity of the contractions. Additionally, deep, rhythmic breathing helps oxygenate the blood, which enhances the "brain-on-fire" effect in the reward centers.
Reduce the "Spectatoring" Effect
"Spectatoring" is when you hover outside your own body, judging how you look or wondering if you're taking too long. This activates the prefrontal cortex—the very part of the brain that needs to shut down for an orgasm to occur. Mindfulness or focusing purely on physical sensations can help bypass this mental block.
Address the Lubrication Factor
Vasocongestion naturally produces lubrication, but it’s not always enough. Friction can turn from pleasurable to irritating very quickly, which sends a "stop" signal to the brain. Using a high-quality lubricant ensures that the physical stimulation remains positive until the reflex is triggered.
Understanding what happens during female orgasm is about more than just "getting there." It’s about recognizing the intricate dance between your blood, your muscles, and your brain. When those three things align, the result is one of the most powerful physiological experiences the human body is capable of producing.
