When you are talking to your quarry, let your eyes stay glued to his or hers a little longer than necessary - even during silences. A gaze that lingers awakens primal, slightly disturbing feelings. It induces the same "fight or flight" chemicals that race through our veins when we feel infatuation. When you must look away, do so reluctantly. Drag your eyes away slowly. This is a particularly good technique for men to use, as women always want to feel that a man is absolutely fascinated by them.
