How does boy meet girl? Is finding a mate ever easy? How do you send out a signal that you're available? There are as many ways to speak the Language Of The Sexes as there are cultures. The Japanese build shrines to the male phallus. Many Muslim women live behind veils. Ethiopian tribeswomen enlarge their lips with ceramic plates, and some Chinese used to crush women's feet to keep them tiny and delicate. Compare all this to America, where women practice gender amplification with silicone breast implants, collagen lip injections and tight high heels. It's easy to see why the Language Of The Sexes is so hard to understand.
