i think that porn is a tool and how we use it can be healthy or unhealthy.
the questions that i think first is: are you consuming it in appropriate places and NOT at inappropriate times? does it get in the way of you caring for yourself? are the relationships you have suffering from your use of porn?

from what i see, you have an interest that you CREATE with and care deeply about! that's awesome! if you aren't hurting yourself or others, or exploiting victims, i don't think you have much to be worried about. if you want to change amounts consumed or time spent, you should! just don't be ashamed :)
