No I bloody do not. Tantric smantric. What a load of crap.
I could not think of anything worse than a ten hour sex session without climax under the guise of some left-wing, new-age voodoo hoodoo sex dictum.
Get on with it. If you want passion get passionate, if you want lots of hugging and petting just do it. If you want a bit of slap and tickle, again just do it.
To plan a tantric session will kill the moment and be a complete let down. Besides, lovers balls is not a pleasant experience.
