<s>[INST] hi sir i am ashish i suffering from nightfall from 2011 since now my age is 19 year and i have problem of nightfall is this natural for health or it is normal for our body or it does require any treatment because i worried about this from last 6 months [/INST] Thanks for asking in Chat Doctor forum In Short: It is normal and not a diseaseExplanation: If you donor masturbate/have sex/ejaculate by any means for many days, your body will try to replace old sperms with new one. SO, with the slightest excitation or during sleep you may have ejaculation. So, it is completely normal and does not need any treatment.  Be happy and enjoy. Hope this helps you. Do let me know. </s>
