Respected Sir, I am 28 year old. I have strong penis and I used to masturbate in early days. I think its about one year, i have less desire in masturbating and my penis is not at all strong and i need more time to make it stand and to eject sperm. My marriage was fixed earlier January this year. I consulted a doctor before my marriage and ask his advice. He told me that after marriage if you get love from the bride everything will become normal and he prescribed me some tablets, Tab Carni Q and tab Nano Leo. He told me to take the tablet 1 hour before intercourse. But after marriage too, I am not able to have sexual relationship due to my week penis. It gets erect for 1-2 minutes, then suddenly it goes down forever. My wife was also very much worried. I consulted the doctor again and he did all my blood and urine investigation. In that he checked my thyroid level also. In that my prolactin was a bit high up to border line. So he advised me to take tab cabergoline 0.25 weekly twice. I am a nursing student in Canada and I came back to canada, but still my problem not get solved. I couldnt have a sexual relationship so far because of this problem. Expecting your reply. Thank You
