His paper names the plump spot below your cupid’s bow, called the tubercle, as the best indicator of sexual satisfaction. So if a you have thin lips, don’t despair. While full lips are commonly associated with sexual prowess, Brody says to focus on that small bump instead of overall lip shape.
Brody gathered his data using an online survey of 258 mostly Scottish women with an average age of 27 years. Participants with a prominent tubercle were more likely to have ever achieved a vaginal orgasm, leading Brody to believe that there is a link between lip shape and sexual responsiveness.
Although skeptics question the reliability of his survey, Brody is no stranger to quirky sex studies. In 2008, he published a paper saying that women with fluid, energetic, sensual gaits have a greater chance of experiencing vaginal orgasms than those with “blocked pelvic muscles.”
