Hi Thank you for asking HCM I have gone through your query.Nocturnal emission is a healthy and normal process.You don t need to worry about that.While masterbation it is usual that most people get an early ejaculation.But if you get a early ejaculation while normal sex or hand job by your partner,then you can practice following: 1.You can deviate your thought to something nonsexual when you about to near ejaculation. 2.You can do squeeze and stop technique or by your partner. 3.You can select sex positions which give less stimulation to penis. 4.You can put a condom or condom with anesthetic which will decrease the excessive stimulation on penis and there by prevent premature ejaculation. 5.You can also stimulate your partner to maximum before getting your self stimulated. If all these not helping then behavioral therapy by a sex therapist or psychiatrist might help you.In case of no improvement by that medications like paroxetine or Dapoxetine will be helpful. Hope this may help you.Let me know if anything not clear. Thanks
