In order to have a truly fascinating sex encounter, a man must understand where to touch and where to steer clear off. When to stop and when to continue, and at what intensity. Of course there are general erotic regions common to all women, but there are significant variations from one woman to another. It's the onus of the would-be partner to find out what turns on and what turns off his woman. This might take months or even years but the payoffs are huge.
