You have the habit of masturbating. Give up masturbation and recover automatically in one month. But you must stop masturbating. Now I have impotence and premature ejaculation and I can't run away. Quit masturbation, these are automatic recovery. Go to quit color and treat the sequelae of sy. It is good to make a kidney-tonifying iron bridge at ordinary times. Do not take medicine. It is too difficult to find a good doctor to take medicine these days, and it may not be effective. Give up color and health care honestly, and give up as a good medicine. It's gonna be okay.
