The Female Love Muscles

Andrew Siegel MD 1/7/16

Optimal muscle functioning is integral to sexual activity. There would be no “jump” in the term “jump one’s bones” without fit muscles that permit the coordinated movements and muscle contractions that are necessary to engage in sexual coupling.

The following is a short poem I have composed about the muscles of love:

 Limber hip rotators,

A powerful cardio-core,

But forget not

The oft neglected pelvic floor.

Sex is a physical activity involving numerous muscles that coordinate with seamless efficiency. Sexual activity demands movement, a synchronized kinetic chain integrating core muscles and external hip rotators in which both pelvic thrusting and outward rotation of the hips work effectively together to forge a choreographed motion. It is a given that cardiac (aerobic) conditioning is a prerequisite for any endurance athletic endeavor, including SEX-ercise.

Three muscle groups are vital for optimal sexual function—core muscles, which maintain stability and provide a solid platform to enable pelvic thrusting; external hip rotators, which rotate the thighs outward and are the motor behind pelvic thrusting; and the floor of the core muscles—pelvic floor muscles (PFM), which provide pelvic tone and support, permit tightening and relaxing of the vagina, support clitoral erection, and contract rhythmically at the time of climax. When these three groups of muscles are in tiptop shape, sexual function is optimized.

The core muscles are a cylinder of torso muscles that surround the innermost layer of the abdomen. They function as an internal corset and shock absorber. In Pilates they are aptly referred to as the “powerhouse,” providing stability, alignment and balance, but also allowing the extremity muscles a springboard from which to push off and work effectively. It is impossible to use your limbs without engaging a solid core and, likewise, it is not possible to use your genitals effectively during sex without engaging the core muscles.

Who Knew? According to the book “The Coregasm Workout,” 10% of women are capable of achieving sexual climax while doing core exercises. It most often occurs when challenging core exercises are pursued immediately after cardio exercises, resulting in core muscle fatigue. 

Rotation of your hips is a vital element of sexual movement. The external rotators are a group of muscles responsible for lateral (side) rotation of your femur (thigh) bone in the hip joint. My medical school anatomy professor referred to this group of muscles as the “muscles of copulation.” Included in this group are the powerful gluteal muscles of your buttocks.

Who Knew? Not only do your gluteal muscles give your bottom a nice shape, but they also are vital for pelvic thrusting power.

The PFM make up the floor of the core. The deep layer is the levator ani (“lift anus”), consisting of the pubococcygeus, puborectalis, and iliococcygeus muscles. These muscles stretch from pubic bone to tailbone, encircling the base of the vagina, the urethra and the rectum. The superficial layer is the bulbocavernosus, ischiocavernosus, transverse perineal muscles and the anal sphincter muscle.

The following two illustrations are by Ashley Halsey from The Kegel Fix:

The PFM are critical to sexual function. The other core muscles and hip rotators are important with respect to the movements required for sexual intercourse, but the PFM are unique as they directly involve the genitals. During arousal they help increase pelvic blood flow, contributing to vaginal lubrication, genital engorgement and the transformation of the clitoris from flaccid to softly swollen to rigidly engorged. The PFM enable tightening the vagina at will and function to compress the deep roots of the clitoris, elevating blood pressure within the clitoris to maintain clitoral erection. An orgasm would not be an orgasm without the contribution of PFM contractions.

Who Knew? Pilates—emphasizing core strength, stability and flexibility—is a great source of PFM strength and endurance training. By increasing range of motion, loosening tight hips and spines and improving one’s ability to rock and gyrate the hips, Pilates is an ideal exercise for improving sexual function.

PFM Training to Enhance Sexual Function: The Ultimate Sex-ercise

The PFM are intimately involved with all aspects of sexuality from arousal to climax. They are highly responsive to sexual stimulation and react by contracting and increasing blood flow to the entire pelvic region, enhancing arousal. Upon clitoral stimulation, the PFM reflexively contract. When the PFM are voluntarily engaged, pelvic blood flow and sexual response are further intensified. During climax, the PFM contract involuntarily in a rhythmic fashion and provide the muscle power behind the physical aspect of an orgasm. The bottom line is that the pleasurable sensation that one perceives during sex is directly related to PFM function and weakened PFM are clearly associated with sexual and orgasmic dysfunction.

PFM training improves PFM awareness, strength, endurance, tone and flexibility and can enhance sexual function in women with desire, arousal, orgasm and pain issues, as well as in women without sexual issues. PFM training helps sculpt a fit and firm vagina, which can positively influence sexual arousal and help one achieve an orgasm. PFM training results in increased muscle mass and more powerful PFM contractions and better PFM stamina, heightening the capacity for enhancing orgasm intensity and experiencing more orgasms as well as increasing “his” pleasure. PFM training is an excellent means of counteracting the adverse sexual effects of obstetrical trauma. Furthermore, PFM training can help prevent sexual problems that may emerge in the future.  Tapping into and harnessing the energy of the PFM is capable of improving one’s sexual experience. If the core muscles are the “powerhouse” of the body, the PFM are the “powerhouse” of the vagina.

Bottom Line: Strong PFM = Strong climax. The PFM are more responsive when better toned and PFM training can revitalize the PFM and instill the capacity to activate the PFM with less effort. PFM training can lead to increased sexual desire, sensation, and sexual pleasure, intensify and produce more orgasms and help one become multi-orgasmic. Women capable of achieving “seismic” orgasms most often have very strong, toned, supple and flexible PFM. Having fit PFM in conjunction with the other core muscles and the external hip rotators translates to increased self-confidence.

Wishing you the best of health,
