Female masturbation leading to squirting requires specific internal and external tactile coordination. The woman uses her fingers to simultaneously rub the external clitoris and penetrate the vaginal canal. The internal fingers curve upward to repeatedly press and stroke the anterior vaginal wall, targeting the G-spot. This consistent friction swells the urethral sponge located just behind the vaginal wall. As sexual arousal peaks, the Skene's glands fill with a clear fluid. The pelvic floor muscles begin to contract involuntarily. The continuous internal pressure pushes against the swollen sponge tissue. A sudden, intense pelvic muscle spasm forces the accumulated fluid out through the urethra. This physical expulsion creates a distinct release of deep pelvic tension, differing mechanically from a clitoral-only climax.
