Tantra like Yoga or Zen, is a path to enlightenment, which has its roots in India. It is nicknamed the "science of ecstasy" and focuses on heightening and prolonging the special awareness and rapport that exists between lovers during lovemaking. This view holds that the greatest source of energy in the universe is sexual, and places high value on ritualized intercourse. Sexual orgasm is seen as a cosmic and divine experience.
Tantric philosophy also teaches that everything is to be experienced playfully, yet with awareness and a sense of sacredness in every gesture, every sensory perception, and every action. The path of Tantra is a spiritual one, which includes and appreciates the experience of our sexuality and sensuality as a conscious meditation, as a flowing together of the physical, sexual and cosmic energies
The art of prolonging the pleasures of lovemaking without reaching a direct orgasm is described in the Kama Sutra, the Hindu sex manual written in the 4th century. "Karezza" is the term used to define a male's practice of pleasuring his partner and prolonging their intercourse by perpetuating his state of climax without actually ejaculating. These so called "dry orgasms", orgasms without ejaculation, are pleasurable, and still allow the sexual act to continue. The art of Karezza incorporates breathing control, meditation, work with postures, and finger pressure into the sexual act. Though sexually biased in its description as written (remember it was the 4th Century), the original focus of Karezza, prolonging the state of climax for a couple's mutual enjoyment, easily translates to both partners actively participating in learning to prolong their enjoyment before reaching orgasm.
