Does the plane smiling lips pouting Julia Roberts or curves Sophie Dahl?
A recent study by the University of the West of Scotland, found that women with a prominent, clearly stated "tubercle" on his upper lip - commonly known as a Cupid's bow - are 12 times more likely to reach orgasm through sex alone. Sophie Luck.
For the study, 258 women aged between 18 and 35 years were asked to describe the shape of lips and sexual habits.
Ninety-five percent of people with a well-defined tubercle said they could achieve orgasm through intercourse, but only 60 percent of people with a less well-defined tubercle can boast the same.
However, those of us lacking in the department of tuberculosis should not be too discouraged, because the same study also found that the shape of the lip had no effect on the ability of a woman to orgasm through other methods. "If you're already having orgasm through sex alone, then great," says Paula Hall, Relate sex therapist. "But what really matters in a satisfying sex life is trust, openness and communication."
And if that does not work? Well, there's a lip liner.
