On Making an End to Lust

Just ask Jesus to take it out of you. And keep asking until He does. If you need to, what helped me was blocking my access to my phone's internet. But then don't establish patterns on your computer, otherwise you'll have to get rid of that, too. Just cry out to Him to purify you. It'll work. 

Also, don't feel guilty about whatever dreams will come your way. All the saints go through that. Lewis, Augustine, Bunyan... if you built up patterns of lust, it'll come out in your dreamspace. It's unpleasant, but it's how it has to be. Don't be worried about stuff like "Succubi" or whatever. Literally, all the Saints had nightmares as that was the only place Satan could get to them. Just get up, wash, and stay out of battle until nightfall. Peace.
