A woman who regularly has orgasms could give her game away just by the way she walks.

In a recent study, Belgian sex experts, who had no prior knowledge of the sexual history of a sample of women, were asked to identify whether or not each woman had regular orgasms, through watching videos of the women walking.

Unbeknownst to the experts, the women were classified into two groups - those who could orgasm through vaginal sex alone and those who could not orgasm at all.

Clitoral orgasm history was not included in the study.

The high rate of correct correlations proved the original premise because it was higher than just the result of a lucky guess.  

Researchers think that better pelvic and vertebral rotation, as well as the length of a woman's stride which might be characteristic of the walking style of women who experience 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," the researchers from Universiti Catholique de Louvain, Belgium, wrote.

They believe that their research will assist in treatment of sexual problems and contributes to the study of the "special nature" of vaginal orgasm.
