This is great news. Guys, if your girlfriend is dryer than the Sahara your pencil dick is not to blame. It her vagina's fault.

The shape of her lips may predict the likelihood of her having an orgasm, says a 2011 study in the Journal of Sexual Medicine. Researchers analyzed the results of an online survey that asked 258 women about the shape of their lips as well as their ability to experience a vaginal orgasm. The results: Women with prominent upper-lip tubercles—the little spot at the midline of the upper lip—have a better chance at having vaginal orgasms. So how could her pout predict her ability to climax? It may boil down to what happens before birth. Whatever shapes a fetus’s tubercle may also shape the same neural circuits that affect vaginal orgasm by the time that fetus grows into a woman, says co-author Rui Miguel Costa, M.A., a grad student at the University of the West of Scotland.

258 women that's it? Seriously, we're not buying this bullshit. That is… without further testing. Women, who'd like further the cause of science, may email Rooster to set up clinical trials.
