In the realm of “Who ever came up with the idea to study that?,” scientists at the University of the West of Scotland decided to look into the burning question of whether the shape of a woman’s upper lip—specifically, her “tubercle,” that little indentation in the middle—is correlated with her likelihood of experiencing vaginal orgasms. And—oh my God! OH MY GOD!—it totally is. (Sorry.) To quote from the study, “A prominent and sharply raised lip tubercle was associated with greater odds of ever having a vaginal orgasm, and also with greater past month vaginal orgasm consistency.” Now, go forth and check out the upper lips of every woman you know.
