This is the first and one of the very common fallout as a result of excessive masturbation / night fall - Premature Ejaculation. It  is a problem which is concerned entirely with the mind and it can be easily cured with the help of herbal formulations because medicinal herbs always acts on the system and not on the symptoms. If after erection, some watery discharge is present then it is a sign of weak muscular structure of your pelvic region due to over masturbation or nightfall which certainly leads to Premature Ejaculation because the valves in the seminal ducts are not potent enough to hold back the flow of fluid while in the process of sexual act. During act of coitus, blood flow to the penis must be sustained and regular which results in hard and long erection and also sustained blood flow ensures, there is no leakage of sperms in between which leads to a much longer duration of sexual intercourse.
