The vagina is not a passive organ. It does more than just receive and accommodate male penetration. During intercourse, the muscles of the vaginal walls contract and move rhythmically to assist with friction and pleasure. This movement is known as the 'pelvic floor muscle contraction' and occurs when the woman pushes her pelvis forward and upward, creating thrusting motions that enhance stimulation.
The pelvic floor muscles are located between the bladder and rectum and surround the urethra and anus. They support the bladder, bowels, and internal organs, including the cervix and womb. When these muscles contract, they tighten the vaginal wall, creating a sucking sensation that can feel pleasurable for both partners.
During arousal, the clitoris and other external genitalia become engorged with blood, while the vagina becomes moistened with lubricating fluid. As sexual tension builds, the woman may experience contractions or spasms in the pelvic floor muscles, which create a pulsing or squeezing effect within the vagina. These muscle movements can be controlled by the woman, allowing her to adjust the intensity and speed of her partner's movements during sex.
The pelvic floor muscle contractions can also occur independently from any external stimulation. Some women report feeling them without touching themselves or their partner at all. This phenomenon is sometimes referred to as 'the kegel' exercise, named after Dr. Arnold Kegel who developed it as a way to strengthen the pelvic floor muscles.
To perform a kegel, simply squeeze your pelvic floor muscles like you would if trying to stop urine flow midstream, then release. Repeat this several times per day to build up strength and control over the movement. This can help improve bladder and bowel control and enhance pleasure during intercourse.
In addition to enhancing intimacy between partners, the rhythmic contraction of the pelvic floor muscles has been shown to increase sexual satisfaction. A study published in the Journal of Sexual Medicine found that women who consciously contracted their pelvic floor muscles during intercourse reported more orgasms than those who did not.
So don't underestimate the power of the vagina - it's an active participant in the sexual act, capable of creating its own sensations and pleasures. With practice, you may discover new ways to use these movements to deepen connection and explore erotic potential with your partner.
