The male partner uses the palm, fingers, or shaft to apply broad, rhythmic friction across the entire female vulva. This wide-area movement stimulates the external clitoral network, labia minora, and the surrounding urethral sponge simultaneously. The continuous tactile pressure increases localized blood flow, causing the pelvic floor muscles to engorge.
This broad sensory input avoids localized oversensitivity while building intense somatic tension. The rhythmic friction stimulates the Skene’s glands located near the urethral opening, forcing them to produce and accumulate fluid. When the pelvic tension reaches a specific threshold, the involuntary contraction of the pelvic floor muscles expels this accumulated fluid externally.
