Thanks for consulting at my virtual clinic. I have carefully worked through your case, and I can realize your health worries. Being your physician, I assure you not to worry as I will take care all of your medical concerns. This probably is due to your masturbation practice when you were young. you can either abstain from masturbating and having sex and stop smoking for a month. which will increase your sex urge and sperm quantity. then you can have intercourse with you wife. Hope it helps. If you need further, detailed and quick assistance related to any health issues in future, feel free to ask me a question directly from my profile. Have a wonderful time ahead. Best Regards! Dr. Arunmozhi varman
