GREAT SEX

So lets give this a test drive:
Great sex starts by realizing that the mind: thinking, thoughts, fantasy, fears, guilt, judgments, all inhibit sex a little or a lot. E. D. is first about thinking instead of paying attention to what you are actually engaged in/doing.

Tantra techniques are designed to quiet the mind first then turn up the sexual energy.
Since you [men and women] don't have to ejaculate to have an orgasm, Tantra is focused on orgasm not ejaculation. There is no ejaculation in formal Tantra and there is a full body orgasmic experience that grows over time.

"Sex, yes I invented it please enjoy it often".
