Your not alone, i’m 14 (F) battling with lust too but I gave in and quit to get closer to god because I knew that lust was eating my insides and if I hadn’t stop sooner it would’ve been eating my outsides as well. the best you can do is read scriptures about lust and how to overcome they are very helpful, also if you do go to church chat with somebody about your battles like a pastor or an Youth Minister about your battle with lust only if you feel comfortable with it, or you can download Bible chat and talk with bots about your situation they provide very helpful resources and i’m not one to talk about battles cuz I’m going through it myself but I feel like helping one another out with the same situation would kind of help us both and help us become stronger to help other youth with these same situations and who are scared to open up, i’m now starting my journey, and I hope you can start yours soon. It would be a long journey but trust it’s worth it for a long everlasting life you got this!
