The most important thing is that you will not be able to get a nervous breakdown from watching a movie, but excessive masturbation may lead to symptoms of nervous breakdown. If you are in a state of nervousness and excitement, and if you masturbate excessively while watching a film regularly, it may lead to dizziness and weakness, weakness of the waist and knees, memory loss, lack of concentration, insomnia and a series of symptoms of neurasthenia, thus affecting normal life and work. It is advisable to read less sex-related stimulating books and magazines, films and videos, to reduce the number of masturbation, to divert attention by doing something that interests you, and to pay more attention to rest and strengthen physical exercise to enhance physical fitness.
