: First of all I must tell you that night fall is a normal thing to happen. Regarding masturbation, you can masturbate more during winter season and less during summer season. For simple reason that cool environment is favorable to compensate the exertion during masturbation while during summer it is difficult restore the exertion caused during the act. Also, one more thing whenever you want to have sexual relationship with your mate I may suggest you that you should not masturbate atleast one month prior to the sex to get best results and to avoid pre-mature ejaculation even if you are scared that you might be suffering from it or just to be on safer side.
