It is about love which often incorporates sex, but it is also about experiencing life. Tantra combines both spirituality and sexuality which helps deepen your self-awareness, bringing about empowerment. Tantra is essentially a sacred way of living.
What works for men, however, does not work the same way for women. We are wired very differently. In fact, men have been wired to orgasm easily and quickly.

Maybe women need to be more vocal.
