Kissing is very intimate. It's a closeness that is personal, passionate, and communicates a variety of things—from the first kiss onward.

A simple kiss is often the initial gauge by which one might judge the success of a relationship. According to scientists who make their careers studying kissing (they are called osculologists), there's an enormous amount of neurotransmitters, evolutionary biology, and instant assessments of potential life-mates.

What she wants in a kiss: Start gently. Let your mouth wander as she allows, but pay attention to her responses. Light strokes on cheeks, neck, and back get extra points, as these areas are usually ignored (at least initially). At the beginning, a light caress is definitely recommended, and should give way to a harder touch and grip as kissing continues. Timing is everything. Start slowly, and stay slow enough to watch for signs that encourage more rapid movement and advances. Kiss her lips, cheeks, eyelids, and neck slowly until she makes it clear she can't handle another second without... more.

Let it build. Kiss her against the wall, kiss her leaning across the front seat of the car, kiss her in the shower... just kiss her. And — be sure to kiss something besides her mouth: nape of her neck, her ankles, her wrists. Slowly and sensually will unlock her passion.
