Secondly, we should treat masturbation correctly. Teenagers get pleasure from nocturnal emission, then play with genitals and form the habit of masturbation, which directly affects their study and work and causes harm to their health. In fact, from a medical point of view, the harm of masturbation is not as terrible as some people say. Of course, excessive masturbation or excessive pursuit of sexual stimulation makes the genitals in a state of congestion for a long time, which is easy to induce adenoiditis. Aspiring teenagers still have to make up their minds to quit this bad habit, focus on their studies and work, and strive for progress.
Finally, teenagers should pay great attention to their health. During this period, we should pay attention to sitting posture and walking posture to prevent the back and spine from bending. In addition, boys should not wear tight pants, because testicles are extremely sensitive to temperature. Often wearing tight pants will make the scrotum skin thicker, and the testis will rise as high as the inguinal outer ring, which will lead to the testicular temperature being higher than the normal temperature and affect the sperm development in the testis. Moreover, tights increase the friction on the penis head, which is easy to cause sexual impulse. Boys should also pay attention to keep the external genitalia clean, often flip the foreskin, clean up the dirt inside, and prevent inflammation and penile cancer.
