Pron addicted

Hello guys, I am 26 old men from Europe. Sorry for my ugly english grammar, please dont judge me to hard!

I am addicted for my live. I start masturbate when I was about 10 years old. When I was 11 , I begun to drink and smoke. With 14 I was totaly addicted. Later mary jane, painkillers and antihypertensive, ampehtamine, cocaine, mushrooms , mollys and other rubbish.
2016 I accepted Islam and stopped all this things by my own. But my porn problem , I try to fight for more than 3 years now. I am engaged and will mary soon. I am really afraid , that my porn addiction could influence my sexual life negative. I already had an bad experiense back in the days. I had an date, but was looking to porn and play on my self. When it comes to sex, I was not able to do something. I was not interested in the girl, because of my freakside.
Nowdays I spens on some days about 1-3 hours ob peace watching porns instead of getting my stuff done. I not study, I am not speaking to my woman, I am not studying , dont do sport. Just watch hour for hour , nonstop. And even I want stop, I can not. I suffer every day again and again. Now I read about nofap in the internet and want you guys help.
