How does your addiction affect you in normal daily life? Does it prevent you from being productive? If there was no God telling you not to do it, would it still consume you and have negative impacts on non spiritual aspects of your life? If so, it is truly something that is an addiction. If you would not struggle so much if you were “allowed” to do it, there is something else that is wrong and it is your religious convictions which are making this an issue and making it cause you so much pain. This is a super common issue and there is nothing wrong with you if you continue to fall. It’s common, it’s natural to have those urges as long as you don’t let them rule your life and obsess with them. I am sure that this discouragement it causes is is making it more difficult to overcome this and probably makes it easier to give in. Maybe you need to adopt a different perspective of the sin and what it means when you fall into it. Celebrate the victories, even Celebrate the falls if they help you grow in humility. And just keep going. That’s the true test. Whether or not you can continue to fight even after moments of weakness. Now that takes real strength. Almost everyone falls into those sins at some point because it’s part of human nature - we are sexual beings
