Well, it's an issue if it's an issue to you. You have a sexual behavior that you can't seem to stop. Obviously, there is a connection to hormones, stress and anxiety levels. If it interferes with your life, relationships and well being then it's self destructive. This is something you'll have to determine. Depending on your religious convictions, masturbation and porn aren't bad.
I would put porn in a whole different category. There are ethical considerations. Again, it's just my feelings. Not everyone has to agree.
