Welcome to Healthcare Magic Premature ejaculation is more of psychological issue than organic cause. Remember you are a very healthy man. Semen coming before sex is only because of anxiety and tension.. You should relax. Masturbation will not cause this problem. It is healthy if not overdone. You should eat fresh fruits and vegetables daily and plenty of water. Avoid junk food, fried food, fatty food, colas, excess coffee. When you meet your partner don;t d sex immediately, you should do more foreplay as women respond to foreplay more than actual sex act and this will help both of you in finding pleasure. Be cool. You will do great.
