Teens - Confessions

When I was little I was curious about what porn was once I watched ur I was addicted but I knew I needed to stop so I did. But now I struggle not to watch it I don't feel right asking for forgiveness everytime I do it promising that I wont do it again I feel like I really need to pray deeply pray and be cleansed of all of this but I just can't seem to fond the real right way to do it
