According to Taoist teachings, in the initial stages of lovemaking the lovers must know how to tease each other until their Yin and Yang energies are in harmony and the partners are of like mind.
When the couple is in the heat of passion, then they engage in intercourse. The penis (which the Chinese also called the Jade Stalk, the Crimson Bird, or the Pillar of the Celestial Dragon) may enter the vagina (the Golden Lotus, the Vermilion Door, the Blossoming Peony Flower, or the Secret Recipient). The Jade Stalk should alternate between slow penetration and deep, strong thrusting.
