Masturbation = jelq + kegel exercise
I think masturbation is a PE exercise in itself. It’s a combination of jelq and kegel exercise. Right now, whenever I feel the urge, I make sure I make the best of both worlds (workout and pleasure) by doing it being conscious of basic PE theories. That means no more backward strokes, just forwards or jelq strokes. Controlling ejaculation is where kegel comes in.
