Hello Thanks for query .You had been indulged in masturbation since many years and now facing problems related to sexual activities. First of all there is myth in a mind of common man that excessive masturbation is the reason of all sexual problems But I would like to state that it has been discussed in scientific forums all over the world and proved scientifically that masturbation does not have any negative effect on any organ or system in the body .All the doubts that you have are mind related and due to anxiety. Though it is harmless, excessive and frequent habitual masturbation does affect quality of erection and delays ejaculation .Please try to reduce the frequency of masturbation by keeping yourself busy in activities like sports ,reading ,social work etc so that you will not get free time to masturbate. There is no reason why you should not have sex with your wife and impregnate her . Dr.Patil.
