[/INST] Hello, The nightfall is common at such a young age. However, if you are feeling excess nightfall then try to watch fewer porn videos and magazines if applicable. You can try yoga and meditation. You can focus more on the study. So night fall is not the disease. But you can follow above measures to prevent it. If no improvement then consults nearby sexologist or psychiatrist for detailed evaluation. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.  </s>
