THERE ARE PLENTY of stressors that can sap your sex drive, and there are just as many ways to liven your libido.

But did you know something as benign as your face shape could have an influence on your sexuality?

Turns out men and women with square face shapes—typified as being shorter and wider—tend to have more intense sex drives than people with circular, oval, or triangular faces, according to researchfrom Nipissing University in Canada.

In two separate studies, published in Archives of Sexual Behavior, researchers polled college students. In the first study, 145 undergrads in sexually active relationships completed a questionnaire about how they behave with their significant others, as well as their desires, motivation, and proclivity to have sex. Participants also submitted photographs of themselves so researchers could determine their facial width-to-height ratio.
