Well Waite did follow 'the' secret tradition ... he just Waitised it and obscured it when he 'struck out on his own' - and developed his own take on it, mixed up with his other stuff (that we talked about before and there is a thread here on the many influences that 'made the man').
Nowadays its relatively simple to track the 'sexual end' of this particular tradition of western esoteric tradition ;
G. D. < German Order of the Gold and Rosy Cross < Order of the Asiatic Brethren ('Masonic') < Frankism < Sabbateanism ('Kabbalistic') .
another branch was what Crowley was working ( as well as his G.D. / A. A. 'inheritance' )
O.T.O. < Hermetic Brotherhood of Light / Hermetic Brotherhood of Luxor * < Order of Asiatic Brethren
This tradition focused more (than the G.D. did) on the male female partnership aspect ; the 'active Shekinah' and produced the first 'western tantrics' * ; P. B Randolph, Max Theon, The HBL 'upper members' ... even Blavatsky in her 'pre-India days'. Their early work was associated with Women's suffrage, sexual rights (and rites ) , and for the purpose of securing the family and producing advanced children (the 'divine child without' ) , this later started being used as a practice for other ends , and (any other usage) caused a great new split ... into a type of 'left handed tantra'.
