What is the harm of excessive watching of movies, excessive sexual thoughts, and excessive discharge of pre-seminal fluid (madhiy) - from a religious, physical, and psychological perspective?

Movies generally contain objectionable elements such as immodest display, gender mixing, music, romantic and obscene language, and viewing them is prohibited due to their violation of the commands of Allah and His Messenger. Their religious, psychological, and physical harms increase with frequent viewing, and they may lead to masturbation or fornication. The harms of watching these movies are similar to the harms of frequently indulging in sexual fantasies, which are considered a psychological disorder if they dominate the mind. Islamic Sharia prohibits these fantasies because they can lead to falling into forbidden acts. They often arise from watching forbidden things and lead to the eye becoming accustomed to them, and may cause spouses to lose interest in each other. Frequent discharge of pre-seminal fluid (madhiy) may be due to strong desire, an ailment, or due to repeated unlawful gazing and sexual fantasies.
