<s>[INST] Dear doctor,i m 27 year old guy who is suffering from the problem of nightfall.It occurs in regular intervals once or twice in a week period. It never do masturbate. I have this problem for about 10 years now. I have not consulted any physician or taken any advise from anyone, but now I am quite worried as i feel very weak and uncomfortable after that.I feel uneasy for the whole day and cant do gym also. Please advice me on problem. Do I need to a sexologist or undergo any treatment. Is it affecting my health and going to affect my future life or damage any of my organ?? Or is it going to affect my sexual stamina in any ways?? solve my issue asap coz I am very much disturbed by this. [/INST] Hithanks for using Chat Doctor Night falls is normal physiological process to take out extra semen out of body. It is not an illness. It happens in those cases, where patient do not do sex or masturbation. There is nothing to worry about it. It does not cause any physical side effects. It would not affect on your sexual stamina or would not damage your organ. There is no need to take any medicine for this. Just do masturbation daily or alternate day. It would stop on its own. In your case, I think u need proper sex education to clear your sexual misconception.  Thanks </s>
