problems and advantage of nofap after 17 day

Hello Fapstronauts,

I'm 15 years old boy, pretty introverted. I started nofap since i quit my 2nd toxic friendship. They treated me like a victim who did not trust himself, a shit that escaped into porn. They were pulling me down. I relativized and i tried to pick myself up after.

I'm currently at my 17th day of no PMO, it's okay, but i have some problems :
- Sometimes I look hentai (just hentai) like 3 minutes a week just to see how it feels and it doesn't me do anything. I think i need to stop but i feel like it doesn't change my streak. It's weird.

- I started PMO at the age of 10 years old, and i was watching porn and hentai about 1 a day, then 1-4 a day (since 1 year). I was always tired, always friendzone. How long will it take to stop thinking about it and later not have a problem with porn?

the benefits and what has not changed since nofap :
Since i stopped, i run, i swim and i do a little bodybuilding (~4-6 hours in all), i have never really played sports in my life and for a man who life behind a screen, it's very gratify.

The problem is that I'm also addicted to the computer and the smartphone, and I spend more time in it than doing sports, i want to reverse the roles.

My motivation for school doesn't change, my relationships with people don't change either.

Nevertheless, i go out and run about 3 times a week in parks. I take more time to enjoy the songs of the birds, the weather.

I think nofap just allowed me to have motivation to play sports, i'm the same as before except now, i have more confidence in what i'm doing. I understood that stopping porn is stopping a way of life but this way of life is always the same. In the end, I did not win much. I hope that in the future, i will be more motivated to consider future projects (only the piano goes through my mind for the moment).
I want to evolve, but i don't know how and where. Stop internet (& video games) and porn would drive me crazy, i can't do both. I'm alone in this fight, i do not have any friends to say it and my family supports me but takes it as an easy change, not as a development of oneself. I take all advices and i would like to thank you for your reading, it helps me a lot.
The porn has probably locked me in a bubble.
