Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern... Excessive masturbation is harmful to both your physical & mental health. However effect on body & physical build is less when you have proper diet. Also feeling of weakness, sleepiness or loss of energy is a common symptom after masturbation. Therefore masturbation should never be done in day time or before work. The fluid like clear discharge from penis on seeing some romantic or erotic scene is secretion of cowper gland. It is normal & you should not worry much about that. To reduce masturbation, Avoid watching sexual/porn content. You should make new friends & try to spend as much as time with them. You should try to focus more on your studies, job, sport activities etc & should avoid watching porn/adult content. In night you could sleep in such a way (wearing tight trousers, gloves, etc) so that your hand does not gain excess to your penis. Hope this information helps Good luck
