At the Universiti Catholique de Louvain, Institut d’itudes de la famille et de la sexualiti, Louvain-la-Neuve, Belgium, they set about proving the theory right.
They took women with known histories of either vaginal orgasm or inability to orgasm from sex and videotaped them walking on the street, and their orgasmic status was judged by sexologists blind to their history.
In the sample of healthy young Belgian women, half of whom were vaginally orgasmic, history of vaginal orgasm that was triggered solely by penile-vaginal intercourse, was diagnosable at far better than chance.
The researchers think that, as well as having an effect on people’s mental health, orgasms can “loosen” muscle groups.
“Research has demonstrated the association between vaginal orgasm and better mental health. Some theories of psychotherapy assert a link between muscle blocks and disturbances of both character and sexual function. In Functional-Sexological therapy, one focus of treatment is amelioration of voluntary movement,” a major newspaper quoted the researchers as saying.
“The present study examines the association of general everyday body movement with history of vaginal orgasm,” they said.
The team said the objective was to determine if appropriately trained sexologists could infer women’s history of vaginal orgasm from observing only their gait.
“Clitoral orgasm history was unrelated to both ratings and to vaginal orgasm history. Exploratory analyses suggest that greater pelvic and vertebral rotation and stride length might be characteristic of the gait of women who have experienced vaginal orgasm.
“The discerning observer may infer women’s experience of vaginal orgasm from a gait that comprises fluidity, energy, sensuality, freedom, and absence of both flaccid and locked muscles.
“Results are discussed with regard to previous research on gait, the effect of the musculature on sexual function, the special nature of vaginal orgasm, and implications for sexual therapy,” they added.
