What's your thoughts on this type of Masturbatig behaviour and how to overcome?

I am a 20-year-old male and masturbate 2 to 3 times a day, sometimes more, due to having too much free time. After reading others' opinions and advice on reddit, I feel very bad about it and want to reduce or stop. What is a normal frequency for masturbation, and how can I control this habit? I would appreciate a genuine answer.
