Hi greetings You are absolutely normal. There is no harm in night emissions or masturbation. It is a sign of virility and proves that you are perfect. One important factor is about any infections in your genital organs like STD. If any history of STD then you need to treat that completely. After that it could be the secretions from your Penis making you feel as semen. Even if semen nothing to worry. Now anything in excess is bad, so you should be restricting watching porn.limit to 5 to 10 min only. Masterbation can be done weekly twice or thrice so that you can enjoy better. You can start some sort of exercises daily to improve your physique and try to learn meditation. You can also concentrate on your studies or professional to divert your mind. Hope my answer helps you. Regards
