The way a woman walks reveals intimate details of her sex life, according to Belgium researchers.
Scientists from the Universiti Catholique de Louvain, Institut d'itudes de la famille et de la sexualiti, Louvain-la-Neuve, Belgium, watched videos of women walking and found that those who have orgasms during vaginal intercourse walk differently.
Researchers videotaped women with known histories of vaginal orgasms and those who could not orgasm during sex walking on the street.
Sexologists, who did not know of the women's sexual histories, were then asked to watch the video and judge the women's orgasmic status.
"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 authors wrote.
Findings, published in The Journal of Sexual Medicine, show that sexologists were able to accurately identify 81.25 percent of the time women who regularly had orgasms from penile intercourse just by watching videos of women walking.
"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," researchers wrote in the study.
Besides having a positive effect on women's mental health, researchers suggest that orgasms can loosen certain muscle groups, making their walk appear more effortless.
"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," researchers said.
Researchers said that the objective of the study was to determine whether there was a noticeable link between general everyday body movement and history of vaginal orgasm, and whether 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," they noted.
"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 concluded.
