Hi Thank you for asking HCM I have gone through your query.You should get rid off anxiety including performance anxiety and stress.You can do breathing exercises to control that if you have that.You should also check your blood sugar level and blood pressures.You can try following techniques: 1.You can perform squeeze and stop technique. 2.You can deviate your thought to something nonsexual when you about to near ejaculation. 3.You can stimulate your partner to maximum before getting yourself stimulated. 4.You can apply a condom or condom with anesthetic which will decrease the excessive stimulation on penis and there by prevent premature ejaculation. 5.You can try different positions which give less stimulation to penis. If all these not helping then you can approach a psychiatrist for behavioral therapy and medicinal management like antidepressants.SSRIs like paroxetine or dapoxetine is usually prescribed for this.Dapoxetine can be used (SOS) when needed also.Hope this may help you. Let me know if you have any further query.
