Why does 14-year-old boy have nocturnal emission in just a few months?

Son, it's okay. It is normal. Being able to ejaculate means that your body has reproductive ability, which means that you have begun to develop, but you are not fully developed. Therefore, frequent ejaculation is too heavy for the internal organs of the body, and of course it is not good for the body. The normal frequency of nocturnal emission varies from person to person. Some people have it in a week, while others may need it for a month. Being able to ejaculate is the ability to have nocturnal emission, which generally means that the number of sperm in the body exceeds the limit that can be stored, so some old sperm should be discharged from the body. Ejaculation reduces the amount of semen, so if you ejaculate generally, there will be less spermatorrhea. However, you are still too young, only 14 years old. It's best not to masturbate all the time (that is, to stimulate the little brother). Frequent masturbation is definitely harmful. But you're normal, as long as you don't ejaculate frequently, it's acceptable once every two weeks.
