Paraclitoridienne: Thanks, Genetic Lottery!

My dedicated readers know that I only read books about sex. This morning I was reading Bonk, by Mary Roach (a gift from J), and came across the following totally remarkable paragraph:

"If the distance is less than the width of your thumb, you are likely to come." This catchy anatomical ditty was penned not by Marie Bonaparte, but by Kim Wallen, an Emory University professor of behavioral neuroendocrinology...Vaginal-clitoral distances, he said, turned out to perfectly predict which women would have orgasms in intercourse and which wouldn't. The cut-off point, as Bonaparte had noted, lay at around an inch--the width of a typical thumb. (p.68)

Translation: If your clitoris is less than an inch from the opening of your vagina, you're significantly more likely to have an orgasm during sex cos that penis will, presumably, rub up against your clit.

The nice French-y word for this physiological state? Paraclitoridienne.

Other interesting details?

"Shorter women tend to have shorter spans [between clitoris and vagina]."

"Women with small breasts seem more likely to have shorter distances." (p.79)

This information has absolutely no use other than to explain why some women can have orgasms so easily and most cannot; but there's nothing to be done about the location of one's clitoris so...thanks, genetic lottery. For the other 80% of women, why not invest in a vibrating cock ring?
