The shorter they stand, the harder they come
Tall girls have it twice as hard in Japan: men their height are rare, and according to the new hit book Sex and Science’s Curious Relationship, (a translation of Mary Roach’s Bonk) they have a harder time getting off during sex, too. Japanese researchers have discovered a high correlation between orgasm ability and the distance between the clitoris and vaginal opening. Because this distance scales with height, the taller a girl is, the more trouble she has reaching orgasm.
