Yep rhythm is a big part of tantric sex. If it's the short short deep you may like this, if you're more of a do'er and less of a thinker you may not.

This method consists of repetitions of 10 strokes each and works like this:

1 rep - 9 short 1 DEEP.
2 rep - 8 short 2 DEEP.
3 rep - 7 short 3 DEEP...etc
9 rep - 1 short 9 DEEP then work your way backwards

best thing about this is who's gonna complain if you add a stroke or 2 to a rep. This is very intese and with varied speeds can produce quite the reaction with most lady friends .

Enjoy,
