If you struggle with porn, masturbation, fornication. Do this. On Mondays, fast till 12pm on Tuesday, ans when you break, by 12pm, eat little, do same on Wednesday till Thursday 12pm and on Friday till Saturday 12pm and eat little. When you fast, your body gets weak to sexual lust. This is how I told many men, and they did overcome. You will need to do it for some weeks, lets say, 8 weeks above. Trust me, you wont die, you will thank GOD for going the hard way.
