Urban Tantra
I had Real Sex on HBO and in one of the segments they had a woman who specialized in "Urban Tantra" which is a technique for having amazing orgasms.
I googled Urban Tantra and there were lots of entries. The summary from a book about it describes it as:
"If you think sexual and spiritual bliss can’t be found in today’s fast-paced world, you haven’t experienced Urban Tantra. With a juicy mix of erotic how-to and pleasure-centered spiritual wisdom, acclaimed sex educator Barbara Carrellas radically updates the ancient practice of Tantra for modern sexual explorers desiring to push past their edge in search of the great cosmic orgasm.
With more than one hundred easy-to-follow techniques for expanded orgasmic states and solo and partner play (as well as more adventurous practices), this in-depth guide reveals the delicious worlds of ecstasy available to all ....."
Funny though. No mention of Karl. I don't know how someone could write an entire book about Urban Tantra inspired orgasms and NOT mention Karl.
Looks like it might be worth looking into.
