<bot>: Thanks for asking in Chat Doctor forum In short: If your penis is at least 12-15 cm when erect, it is not micro penis. Explanation: In your age ejaculation during night and when thought about sex is normal. I think you are taking treatment for erectile dysfunction in homeopathy. Self medication is dangerous.  If your penis is erect when you wake in the morning after deep sleep then you don't have any problem. If you think you have premature ejaculation, do visit an allopathic doctor to get yourself examined before getting disheartened. Your hair and eyesight problem is not related to this, this is your imagination and thinking as for as I think.
