We've been thinking about sex all wrong. Mainstream media, movies, and porn have taught us that sex = penis + vagina, and everything else is just secondary. Standard penetration is how men most reliably achieve orgasm. The problem is, women don't orgasm this way. We've separated our most reliable route to orgasm - clitoral stimulation - from how we feel we should orgasm - penetration. As a result we've created a pleasure gap between women and men.

The tipping point is that magic moment when an idea, trend, or social behavior crosses a threshold, tips, and spreads like wildfire. Just as a single sick person can start an epidemic of the flu, so too can a small but precisely targeted push cause a fashion trend, the popularity of a new product, or a drop in the crime rate. This widely acclaimed bestseller, in which Malcolm Gladwell explores and brilliantly illuminates the tipping point phenomenon, is already changing the way people throughout the world think about selling products and disseminating ideas.
