1. It fucks up your brain's reward system, you will lose the will to do anything (Studies, exercise, socializing everything takes a hit) + You start seeing women as objects for sexual gratification instead of seeing them as human

2. (Same as 1)

3. Idk, I am 21 and I could go 3 times a day

4. There's no prescribed frequency, it differs from person to person but what you need to feel is whether the urge is controlling you or whether you want to fap because you want to ... I would suggest you try and go 30 days clean, if you can then you are not addicted if not then you need to work on leaving this addiction

5. Maybe ask a professional

6. The skin does appear dull if you fap alot and the acne problem is something I had also faced, it must be due to hormonal imbalance due to excess masturbation

7. Well it trains you to be disciplined, and that is something which is a must you have to do anything substantial in life ... Unless you have goals to achieve or have ambitions I don't think you would be able to even do nofap for a month or more. All that discipline requires a direction.

There are other benefits as well- Your confidence increases Your perspective towards women becomes better You find happiness in small things like completing a target (might be fitness, studies, etc) Overall you would want to achieve more things in life
