Why no speak of chastity?

[JesseC]

Leo,

Your teachings are profound and life changing. I am grateful for this access to knowledge.

But most, if not all, the teachings that have led me to you, speak of the power of chastity. Not to be confused with celibacy. More accurately stated, sacred sex. Sex with a spouse without orgasm. The energy that is 'wasted' on orgasm can be 'transmuted'. I can speak from experience that there is some truth to this. And its not just about the physical facet of orgasm, but all of the energy and emotion that goes into the pursuit of such....plus much much more.....

Comprehension of lust, desire, ego are ( or better said, can be) outcomes of this process. 

 Is this a topic that has merit?
