Without getting into specific techniques, the general skill levels from my experience seem to be: Level 0: A fast wank to make the client cum fast Level 1: Slow and sensual cock rubbing, twisting Level 2: Same as level 1, plus using the other hand to massage the balls and other parts of the bodyLevel 3: Same as level 2, plus sensing when the client will cum, and then removing hand from cock before cumming, to edge client. Repeat for 20 minutes before finally releasing for a massive orgasm
Along the same lines, I came across these, which seem to be an instruction manual for erotic massage techniques... Hidden Image/Members OnlyHidden Image/Members OnlyHidden Image/Members OnlyHidden Image/Members Only
