Osho

 In orgasm, you come to this deepest layer of your body where matter no longer exists, just energy waves; you become a dancing energy, vibrating. There are no longer any boundaries to you - pulsating, but no longer substantial. And your beloved also pulsates.

Now, sexual orgasm needs time - the longer, the better; because then it will go deeper into your being, into your mind, into your soul. Then it will spread from the toe to the head... every fiber of your being will be throbbing with it. Your whole body will become an orchestra and it will come to a crescendo.
