A: First, I will say again that Tantra is not for heterosexuals or only for couples. The Kama Sutra refers throughout the discourses on the lovemaking of same sex couplings. References to same sex couplings are found in all the traditions that comprise the erotic sentiment. India, China, Tibet, Egypt, Persia all produced teachings that included same sex unions.
Next, if you want to become an adept in the practice of Tantra you must have an individual practice. If you were to find a teacher, they would instruct you to meditate, make your body flexible and lithe, and develop both spaciousness and reverence. When the teacher felt you were ready they would begin to transmit their teachings to you. When two practitioners who have become grounded in their practice meet in the sexual embrace, a great union can be made. People in the West prefer to jump over the preparation stage and go for what is called Tantric Sex, often what they get is the "lite" version. From what you say, you and your beloved had a true and wonderful meeting. It is possible to cultivate a place for ecstasy, reverence, and communion in your lives through practice. Start alone and then meet.
