Hi, I can understand the mental agony you are going through and I assure you that I ll help you to come out of this situation. Look,it is not unusual to have episodes of erectile dysfunction at some point of life. There are several reasons for this but at your age it can not be pathological. Stress to perform is mostly the reason of this erectile dysfunction and when one or two such episodes happen you become scared. Usually what happens that before the sexual act you become so tense that this anxiety ruins the erection.More you are anxious to perform more the problem increases. So what I suggest you that please take a break,talk to your wife about it and take her in confidence and be calm.Do not over try and I will suggest you not to plan your sexual activity in advance. Please follow my advice and just be with your wife,do foreplay and just decide that you will not indulge in penetrative sex for next few days except kissing and some foreplay. Just be calm and as you will not have that anxiety to perform,you will see that you will get natural erection after a few days and then you can indulge in the real act. I am almost sure that the anxiety and subsequently the fear to perform is the main culprit and so you have to come out of it. One or two successful intercourse and you are through.It s just the matter of confidence. One you get the confidence back,nothing will stop you. Taking Manforce for sexual act is not bad as long as you are not taking it daily and yes,your wife has to be understanding to begin with. I hope,I answered your question. Best of luck. Thanks, Dr.Prabhas Verma
