You know that dip in your upper lip? Well it has a definitively unsexy name: the tubercle. Anyways, the shape of woman’s tubercle may determine wether or not she is able to experience vaginal orgasm. Vaginal orgasms are orgasms from penetration as opposed to orgasms from clitoral stimulation. Many women have difficulty reaching orgasm especially vaginally.
A new study posits that a prominent tubercle may be a genetic marker of vaginal orgasm ability. Genetic Marker?! What’s that?!
[Insert crappy biology lesson by totally unqualified blogger] So humans only have 23 chromosomes that carry our genetic information, but we have, like, a bajillion different genes. So a bunch of different genes are bunched into each chromosome. So often if you have one trait it means that you’re likely to have another one too. So trait A is a genetic marker (means you probably have) trait B, because they were passed on to you through the same chromosome. This is why, hypothetically, that if one of your parents gave you the gene for having vaginal orgasms, they also gave you the gene for having a prominent tubercle, or so this study claims. [End of terribly simplified explanation]
So, the more prominent and sharply raised your lip dip is, the more likely you (and your children) will have penetrative orgasms! For all the other women, fear not! Clitoral orgasm ability is unaffected by lip shape.
