New and whatever

Hello everyone, my name is Sam and I am currently 16.
So a bit about me, I am born in India but I consider myself more Australian since I've lived in Australia my whole life.
I started masturbating and looking at porn when I was 13 years old, at the end of 2012 back in India. I just came across it and went "what harm can it do?" Oh how stupid I was.
I am a Christian and since it is against my religion to do this type of stuff, I feel really guilty that I am being not a good Christian at all. I have been possibly addicted to porn and masturbating since I was 13 and it has been 2 and a half years. Whenever I think of quitting I'll always say "tomorrow I'll stop." Those attempts have obviously failed. I don't know why I even masturbate or watch porn to be honest, like I mean I am enjoying life but eh. It just happens you know and I want to quit.I stumbled across this website through Reddit. I was browsing the Christianity website when a comment linked to r/NoFap. I thought "hmmm what is this website all about." So I read some stuff and well here I am creating a thread.

So with that in mind. I want to start the challenge for 90 days. Hard mode. Every sort of PMO banned. I hope to see some other threads soon and good luck to everyone and hope you all succeed. Advice would be very much appreciated as well!
