THE JERK
Because the testicles have to come close to the body in order for ejaculation to occur, jerking of the testicles away from the body will prevent ejaculation. Place the thumb and index finger around the upper part of the scrotum, and pull downwards firmly.

SUBLIMATING THE SEXUAL ENERGY
More important than any technique you learn is how to sublimate the sexual energy and make it circulate through your entire body.

If the sexual energy continues to build up at the level of the genitals, at a certain moment it may become too much for you to control, and it may burst out in the most direct possible way: through ejaculation.

However, if you sublimate your energy, you will notice that the intensity of your pleasure is much easier to bear and control. This is also the secret of having multiple all-body orgasms. So imagine and mentally direct it up along the spine, like it was being pushed up by the contractions of the perineum.

SELF-PLEASING EXERCISE IN ORDER TO BECOME ABLE TO DISTINGUISH BETWEEN ORGASM AND EJACULATION
1. Lubricate your penis.

2. Touch yourself on your abdomen, nipples, and thighs before passing on to the penis.

3. Please yourself, but remember to stimulate the whole penis, scrotum and perineum.

4. Try to be aware of the degrees of arousal: notice the tingling at the base of the penis, the stages in your erection, the modifications that appear in the cardiac and respiratory rhythms.

5. When you feel you are getting close to the point of no-return, stop, take a deep breath, and contract the PC muscle. You may also avoid ejaculation by pressing the point between the anus and sexual organs, using the jerk method, pressing the head of your penis, and by focusing mentally.

You may even experiment with all these techniques, in order to see which one suits you best. You may even try two or more at the same time, the most important thing is to pay close attention to your arousal and stop in time.

6. If you feel that the sexual energy becomes too strong for you to control, try to make this energy ascend with your mind while you contract the PC muscle a few times. If you still feel that it is too difficult for you to control, stop for a minute and focus on your breath.

7. Pay attention in order to perceive the contractions of the PC muscle and of the anus, contractions that come along in the contractile type of orgasm.

8. After several peaks of the non-ejaculatory orgasm type, you should stop. After this kind of lovemaking, you will feel peaceful and full of vigor and energy. Try to perceive the sexual energy circulating through your body, perceived as tingling, slight itching or stinging, but pleasant nonetheless.
