Struggling with pornography

I think I was about 13 or so when I first started watching it and it was just curiosity and fun at first. Well fastforward to me @ 22 now and I still struggle with keeping my feelings in check and not succumbing to my temptations. I've been trying for so long to be a good Christian young woman like God wants for me but idk how to really do that. Any tips? Pls pray for me
