Does over masturbation make my erection weak? please, need some answers?

Man up!: If somebody has told you that enjoying your body will cause impotence later, they were lying to you. You have probably noticed that after you have an ejaculation, you have a refractory period during which you won't get an erection. This period gets longer as you get older, even during your 20s. If this is all you're observing, don't worry. You owe it to yourself to learn about your adult body.
