I bought and read your book and found it a nice approach that I will certainly try. My interest in sacred sex comes from Samael Aun Weor (I found your site via gnosis-usa).
Your approach is easier to sell (I mean to my wife :-)), compared to Samaels rigid and esoterical views. Especially since the scienctific translation and implication that you made are more easily understandable to more scietifically inclined persons. I thank you for that.
Anyway, my question would be in how much you follow this tradition (not entirely I read in you book since you recommend the use of contraceptives). And more specially the use of pork. Does it seem to affect the sacred sex? Or the nighly orgasms.
