The G-spot is a sensitive area on the front wall of the vagina, roughly 2 to 3 inches inside, that can produce intense pleasure when stimulated. Despite decades of debate, most researchers now view it not as a single anatomical “button” but as a zone where several structures overlap, including the internal portion of the clitoris, the vaginal wall, and a pair of small glands near the urethra.
Where the G-Spot Is Located
If you insert a finger into the vagina and curl it toward the belly button, the slightly ridged or spongy tissue you feel on the front wall is the general area people refer to as the G-spot. That tissue sits directly over two small structures called the Skene’s glands, each about the size of a blueberry, positioned on either side of the urethral opening. These glands develop from the same embryonic cells that become the prostate in males, which is why they’re sometimes called “the female prostate.”
The sensitivity of this area varies significantly from person to person. Some people find direct pressure on the front vaginal wall highly pleasurable, while others feel little difference compared to surrounding tissue. This variation likely comes down to differences in nerve density, the size of the Skene’s glands, and how close the internal branches of the clitoris sit to the vaginal wall. Rather than a fixed spot with clear borders, the G-spot is better understood as a region where multiple sensitive structures converge.
What Happens During Stimulation
During arousal, blood flow to the genitals increases, causing the tissue around the vaginal wall and Skene’s glands to swell and become more sensitive. Heart rate, blood pressure, and breathing rate all rise. As stimulation continues, the muscles surrounding the vagina may begin to twitch or spasm, and many people report a building sensation of pressure, sometimes described as similar to the feeling of needing to urinate. This pressure sensation is common and comes from the proximity of the stimulated area to the urethra and bladder.
Orgasms from this type of stimulation can feel different from those triggered by external clitoral contact. People often describe them as deeper or more diffuse, spreading through the pelvis rather than concentrating in one point. That said, orgasm experiences are highly individual. The release of endorphins afterward typically produces feelings of relaxation and well-being, and the skin may flush across the chest and face.
Female Ejaculation and Squirting
G-spot stimulation is closely associated with two related but distinct phenomena: female ejaculation and squirting. They’re often conflated, but researchers have identified meaningful differences in the fluid involved.
Female ejaculation is the release of roughly 1 milliliter of thick, milky white fluid from the Skene’s glands. This fluid contains high levels of prostate-specific antigen (PSA), fructose, and glucose, giving it a biochemical profile similar to components of male semen. It can happen with or without orgasm.
Squirting is a separate event involving a much larger volume of clear fluid, sometimes exceeding 100 milliliters. Ultrasound studies have traced this fluid’s origin to the bladder. In one well-known imaging study, researchers confirmed that participants’ bladders were empty before arousal, filled noticeably during sexual stimulation, and emptied again at the moment of squirting. The fluid contains urea, creatinine, and uric acid, all markers consistent with dilute urine. However, in most participants, the squirted fluid also contained small amounts of PSA, suggesting that Skene’s gland secretions mix in during the process.
Both phenomena can occur simultaneously, which is why squirting fluid sometimes contains traces of the same compounds found in female ejaculate. Squirting is estimated to occur in about 5% of women, making it far less common than pornography might suggest. The release is involuntary and can happen before, during, or after orgasm.
Why the G-Spot Is Controversial
The scientific debate around the G-spot centers on whether it qualifies as a distinct anatomical structure. No dissection study has identified a unique cluster of nerves or tissue that exists in every person at the same location. What researchers consistently find instead is that the front vaginal wall sits over a complex of structures, including the Skene’s glands, the urethral sponge, and the internal legs of the clitoris, all of which can contribute to sensation when pressure is applied through the vaginal wall.
This doesn’t mean the pleasurable sensations people report are imaginary. It means the experience likely results from stimulating multiple structures at once rather than pressing a single dedicated organ. The size of the Skene’s glands, the extent of the clitoral network, and individual nerve distribution all vary, which helps explain why the same technique produces very different responses in different people.
Practical Considerations
Because the G-spot area sits on the front vaginal wall, positions and techniques that create pressure toward the belly button tend to be most effective for people who enjoy this type of stimulation. A “come hither” motion with a finger is the most commonly described approach. External pressure on the lower abdomen at the same time can increase sensation by compressing the tissue from both sides.
If stimulation of this area doesn’t feel particularly pleasurable, that’s entirely normal. Sensitivity in this region falls on a wide spectrum, and there’s no evidence that G-spot responsiveness correlates with sexual health or function. The initial sensation of needing to urinate is also normal and typically fades as arousal builds, though it can persist, especially given the anatomical overlap between the stimulated tissue and the bladder and urethra directly behind it.
