If sex is a series of comprehensive exams, then kissing is the introductory test. A high-quality kiss can accurately convey your love and compassion to your partner. Recently, the British "Men's Health" magazine gave out 3 kissing steps, hoping to help people capture the heart of their lover in one fell swoop.

Hold your tongue. Whether it's a brief kiss or a French kiss that goes straight in, don't let your tongue act as the "first march", especially don't suddenly stick it out during the first few seconds of the kiss. Generally speaking, a playful kiss can achieve the best "passionate effect".

Gently bite your upper lip. Studies have found that women’s upper lips have a richer nervous system than their lower lips. Husbands can nibble, lick or even bite their wives' upper lips to excite every erotic nerve.

Care for your neck. The neck is the most overlooked sensitive area. As your lips travel across his or her cheeks, kiss your way down to their neck. The skin is thinnest here, and nerves and blood vessels are closer to the surface. A light kiss can get more responses and ignite the flame of love instantly. German psychologists have found that kissing your husband's lips and neck every morning can improve work efficiency and enhance immunity.
