Orgasm: pain

If you have intense pain, you are probably pushing too far forward or too late. When this happens,
the urethra, which is like a hose that has been pinched, swells up with fluid and can hurt. You need
to turn off the faucet before the water (or, in this case, semen) enters the hose. Make sure you push
farther back and/or sooner next time. Also make sure you are not pushing too hard. Some discomfort
is common, especially during the first few weeks, from the pressure you apply with your fingers and
the fluid pressure in your pelvis, but it shouldn't hurt for long. If you are experiencing pain, try to
refine the technique or forget this stopgap measure and learn the more important Big Draw.

A small amount of semen will leak out once you lose your erection, so this is not a method of birth control or safe sex. Using it with other forms of contraception, however, will improve their effectiveness. Since you still lose some of your energy with this technique, the sooner you are able to learn the Big Draw, the better off you will be. Although at first you  may feel fatigued, your energy will return sooner than if you had ejaculated.
 This is a powerful practice, which you should not use more than once every two or three days when you start. If you are elderly or ill, you should not use this practice more than twice a week when you begin. The retained sexual energy may cause you to feel hot or thirsty. If so, try drinking more water. After you have practiced this technique for one to three months,  and  sometimes  sooner,  you  will  notice  your  sex  drive  increase  and  your  erections  become  more  frequent. Increase your sexual activities (solo and duo) moderately; try not to overdo it.
