I came across this prescription for a tantric exercise. What it said was that I should lift my legs in the air for a certain amount of time, clench the PC muscle for 30 seconds and then flutter it for 10 etc.
I have let go of most of it. Keeping track of the time makes no sense in a tantric exercise, because it is just a distraction. What does matter, though, is the essence of it: Approximate, by breathing and muscle tension, what happens during orgasm, without ever touching yourself - and you'll experience all kinds of wonderful feelings. Experiment with your rhythms, develop your own style, and don't be fooled by metaphysics.
I actually do have more energy now. I'm getting my latest narrative finished, after 2 tough years. I stand up earlier than I used to, with less problems, and I'm not so sleepy at night. Even though this is a time of rather hard job demands and a firm and tense timeline.
Definitely awesome, this.
