The C-spot is the clitoris, specifically the small, visible nub (called the glans) located at the top of the vulva. It’s often referenced alongside the G-spot as one of the body’s key erogenous zones, but unlike the G-spot, the C-spot’s anatomy and role in pleasure are well established. With over 10,000 nerve fibers packed into a structure smaller than a fingertip, the clitoral glans is the most nerve-dense tissue in the human body.
But the glans you can see is only a fraction of the full picture. The clitoris extends deep into the body in a wishbone-shaped structure that surrounds the vaginal canal, which means the C-spot’s influence on sensation reaches well beyond its visible surface.
Where the C-Spot Is Located
The external part of the clitoris sits at the very top of the vulva, just above the urethral opening and below the pubic mound. The inner vaginal lips (labia minora) meet above it to form a small fold of skin called the clitoral hood, which partially or fully covers the glans when it isn’t engorged. In many people, the glans is visible when the hood is gently retracted; in others, it’s more concealed.
Internally, the clitoris is far larger than most people realize. Behind the glans, a shaft (the clitoral body) descends into the pelvis and branches into two leg-like structures called crura that straddle the vaginal canal. Two additional bulbs of erectile tissue sit between these legs and the vaginal wall. MRI imaging shows the entire structure resembles a boomerang folded back on itself, held in place by a ligament. From tip to tip, the internal clitoris can span 9 to 11 centimeters. The glans is the only part that isn’t erectile tissue, but it is the most densely packed with nerves.
Why the C-Spot Is So Sensitive
A 2022 study from Oregon Health & Science University counted the nerve fibers running through the dorsal clitoral nerve and found an average of roughly 10,281 nerve fibers serving the clitoral glans. That’s significantly more than earlier estimates of around 8,000, which were based on animal studies. These nerve fibers are bundled into a pair of dorsal nerves, one on each side, that converge at the root of the clitoris where all the internal erectile tissue meets.
This concentration of sensory fibers in such a small area is what makes the C-spot extraordinarily responsive to touch, pressure, and vibration. It also explains why direct stimulation can feel too intense for some people, particularly without adequate arousal first.
How the C-Spot Differs From the G-Spot
The G-spot refers to a sensitive area on the front (anterior) wall of the vagina, roughly 2 to 3 inches inside. While the C-spot is external and easy to locate, the G-spot’s exact nature has been debated for decades. Some researchers have described it as a distinct patch of erectile tissue behind the pubic bone. Others have found that the proposed G-spot location sits directly over the internal legs and bulbs of the clitoris, suggesting that G-spot stimulation may actually be stimulating the clitoris from the inside.
This distinction matters practically. The C-spot responds to surface touch on the vulva. The G-spot responds to internal pressure through the vaginal wall. But given how the clitoris wraps around the vaginal canal, these two zones are likely part of a connected system rather than completely separate structures. Stimulating both simultaneously tends to produce more intense sensation than either alone, which makes anatomical sense if they share the same underlying nerve network.
How Sensitivity Changes Throughout the Month
The C-spot isn’t equally sensitive every day. Ultrasound studies tracking the clitoris across the menstrual cycle found that clitoral volume increases progressively through the first half of the cycle, peaking around ovulation when estrogen levels are highest. Blood flow to the clitoris also increases during this window, as the arteries supplying the area relax and allow more circulation. After day 20 or so, both volume and blood flow drop back toward baseline as hormone levels fall in the premenstrual phase.
This means the C-spot is physically larger and better supplied with blood around ovulation, which can translate to heightened sensitivity. Conversely, the days just before and during menstruation may bring reduced responsiveness for some people. These shifts are driven primarily by estrogen, which triggers the release of nitric oxide, a molecule that relaxes blood vessel walls and increases engorgement.
Stimulation Basics
Because the C-spot is so nerve-dense, jumping straight to direct contact often feels uncomfortable or even painful. Starting with indirect touch, like stroking the labia or circling around the clitoral hood, allows the erectile tissue to begin filling with blood. As arousal builds, the glans becomes slightly more exposed and better cushioned by the engorged tissue beneath it.
Once you’re ready for more direct contact, lighter pressure tends to work better initially. Sliding motions (up and down or side to side across the hood and glans) are a common starting point. From there, increasing pressure or speed based on what feels good lets sensation build gradually. Many people find that consistent, rhythmic motion in one pattern works better than frequently switching techniques.
The internal structure of the clitoris also means that vaginal penetration can indirectly stimulate the C-spot’s deeper components. Positions or angles that create pressure against the front vaginal wall press into the clitoral bulbs and crura, adding a layer of internal stimulation. This is one reason why combining external clitoral touch with penetration tends to be more effective than either approach on its own.
Why the C-Spot Was Overlooked for So Long
For most of modern medical history, anatomy textbooks depicted the clitoris as little more than the tiny external glans. It wasn’t until 1998 that urologist Helen O’Connell published detailed dissection work revealing the full internal structure. Her later MRI studies showed that previous anatomical illustrations had been based on cadaver dissections where the clitoris was positioned unnaturally, rotated more than 90 degrees from its actual orientation in a living body. This made the internal structures appear smaller and less significant than they are.
O’Connell’s imaging showed the clitoris is a broad, multi-part organ with extensive attachments to the pubic bone, urethra, and vagina. The erectile tissue of the bulbs and crura is substantial, comparable in volume to the erectile tissue of the penis. This research reframed the clitoris from a minor anatomical detail into the central structure of vulvar sensation, and it’s the reason the term “C-spot” now carries more anatomical weight than it used to.
