In 2011, a study came out suggesting a possible connection between orgasm rates and women’s lips.
In the study, 258 women were asked about their sexual activity levels and corresponding orgasms, along with age and the prominence of the tubercle of their upper lip.
This refers to the area located in the center of the upper lip. See below.
Apparently women with prominent upper lip tubercles had greater success with achieving vaginal orgasms.
Interesting to note the study was specific to vaginal orgasms, not masturbation or oral stimulation.
Looks like our lips…and our lips might be more closely related than we thought.
Sorry, Kylie Jenner, fillers don’t count.
