Phil Ayesho,
From what you write, you haven't done Tantric non-ejaculatory orgasm properly yet. There is no retrograde ejaculation, and what results is what helgaleena described and what I experienced, and that is a full-body orgasmic experience that totally drowns out any penile contractions. If my penis were contracting, the pleasure is so intense that I would not notice. Also, at my age, any ejaculation will take a toll, but I remain totally hard. I tried to learn Tantra from books but didn't feel I had it under control. So I re-learned it from scratch the way it's meant to be learned, with a woman who's been trained in the arts. And then I was able to practice it properly, except that I don't go with the ejaculation drains energy theory, and I always ejaculate at the finish. Ejaculation is good for the prostate, which would not have been known ages ago.
My view of Tantra is that it's partially sexist, and women don't gain much benefit from some aspects. My multi-orgasmic capacity or my whole-body orgasms don't bring much pleasure to my wife, for example. Certainly bring a lot of pleasure to me, though, and it's nice to be able to control orgasm and ejaculation rather than having it randomly control us. Other aspects, such as the unity of yin and yang, are certainly of equal pleasure to male and female, but that's not the whole purpose of Tantra.
One final point is that African women are not black, the feminine is lighter than the masculine, and they are actually a dark ebony brown. But I will explore her next time, and see if I can pick the flush you described. I doubt it though, as I probably would have noticed given I've had sex with her a few thousand times in various positions, and I suspect I would have discovered extra heat from her breasts before now.
