Do I Need to Have a Partner in Order to Practice This?

Tantra can be practiced either solo or as a couple.

The solo path is known as White Tantra and includes disciplines which prepare the body for sustaining high levels of sexual energy for prolonged periods of time.

The practice of Red Tantra is when lovers engage in a dance of erotic energy that opens them to discover increased love and intimacy between them.  Naturally, the intensity increases as you share this practice with someone you care about.
