Life is a continual dance of polarity. The ancient tantrics knew it. And anyone who regularly enjoys mind-blowing sex and happy relationships knows it.
Tantra is Hinduism’s rebellious branch. Only later was it appropriated by other Eastern religions, and is usually presented in this updated way to the West.
When a man experiences sexual stimulation over a long period of time, and manages to prevent himself from tipping over into ejaculation, he starts to experience full-body orgasm.
