Nofap can be quite the challenge, but it depends how hard you make it upon yourself and how determined you are to overcome your addiction. It boils down to your DEDICATION.
My advice is that you completely shove away any urges. Stop looking at anything that'll turn you on. Block porn sites, stop looking at sexy pictures, etc, etc. And when you DO get horny, occupy yourself IMMEDIATELY. Go outside, play some sports, do whatever you can to OCCUPY yourself. DO NOT TOUCH YOURSELF!!! It's simple, just don't touch yourself. Keep ya hands outta ya pants, and you should do fine.
I've been on NoFap for about a month now. I've been doing just fine. Yeah, I'm super horny most of the time but the thought of masturbating just disgusts me.
