Open your mouth slightly, lick your lips or chew them, show the underside of your tongue, smile voluptuously, touch your upper teeth with your tongue. You're sure to get your message across. When you're flirting, it's important to appear approachable, so don't cover your mouth or hide your face behind your hands.

Be generous with your smiles. A smile says that you are approachable, that you are a kind, sociable, nice person.

Study the gestures of the target of your flirting, the way he/she toys with a cigarette or lifts a pencil or a finger to his/her lips. The gesture may be unconscious, but it reveals that the person's interest has been aroused.

When a woman is aroused sexually, her lips fill with blood and they become slightly swollen and very red. Lipstick was invented thousands of years ago to mimic this reaction. Today, it is no longer bad manners to apply lipstick at the table.
