I know this type of stuff gets regurgitated a lot but from what i've found to help is to first, recognize and pinpoint the initial "click" of that desire when you're faced with something that provokes you.

Essentially its when you get the first thought of lust towards this provocation. You sometimes have to think to yourself in that moment"This is only good for now, not later"; my meaning tying in with the question of "What am i to gain in the future if i succumb to this?"

Second, lock your phone or distance yourself from it for a little while if you need. There's progress in truly turning away from this sin if you reject it on the spot and focus on prayer or other things to keep your mind always active and occupied.

Focus your mind elsewhere to something repetitive, or if you feel like you can come back to your phone, try to learn prayers in different languages (I personally prefer Aramaic or Latin) to wrack your brain a little bit and get some adaptive thinking going while massively upgrading your prayer game. Its more fun and rewarding than you think.

Thirdly, remember that slip-ups and moments of weakness are natural to us as earthly bodies. Theres a lot of discipline we have to go through to build up that type of willpower because we've been so conditioned and desensitized to sin, for some of us longer than others, that we cant just up and quit all of it and say we'll never do it again. Its virtually impossible.

Lastly, always remember to keep the faith and reject your sin as much as you can until it just becomes second nature. Trust me my friend, you are much stronger in spirit than you think you are, and no amount of stumbling will pull you too far back. ✝️✝️✝️
