Kegel exercises are often dismissed as not being 'real PE' but they play an important supporting role:
WHAT KEGELS DO:
Strengthen the pubococcygeus (PC) and bulbocavernosus muscles — the muscles that drive blood into the penis during erection and control ejaculation. Stronger PC muscles = harder, fuller erections.
PE RELEVANCE:
Harder erections from stronger muscles means you're working with better baseline engorgement in jelq sessions
Reverse kegels (relaxing the muscle) are used during jelqing to allow maximum blood flow
Kegels used during squeeze techniques to maintain pressure
BDSS (blood distribution stretch sequence) uses kegel pulses during stretching
DOES IT ADD SIZE?
Not structurally. But optimal muscle function means optimal erectile function — which can mean fuller, firmer erections that appear and function better. That's meaningful even without structural change.
