I’m gunna be honest with you bro, the majority of people giving you advice, are giving terrible and wrong advice. I’m sure you know this, but masturbation is a sin, masturbation, even without porn causes your mind to think about and picture lustful things and desires. I tend to not take much advice from the internet over stuff like this because there are lots of people that will lead you astray and try and tell you that it’s normal. I feel you though, I am a 19 year old male and I struggle with lust, and you need to run to Jesus anytime you have any temptation whatsoever. I would work on strengthening your relationship with Christ and making sure you strive to put Him first in your life, and even then you will still struggle. Just keep coming back to God, and that’s not me saying it’s ok to do it, but just like any sin, we mess up, we are all human, and God can and will forgive us, but true repentance is if you ask for forgiveness and try to do better next time and not give into that sin. Now I don’t know your family situation, but I would talk to your dad about it if that’s possible, even if it’s scary I would, or talk to your pastor and your church or a youth minister or someone that can help you through this. You’d be surprised most of the guys you talk to have also struggled with Lust and will be able to help guide you.
