I'd say you're on the right track.

Plenty of people love pornography of all different types and it doesn't affect them negatively in the slightest.

Then there are people who were brought up to believe that it's something to be condemned and therefore feel depressed when they indulge in it.

Then there folks like me. I was never influenced or coerced to believe that sexuality or pornography were "bad" things and I am very open to other people viewing and enjoying the stuff. But my own indulgence makes me heavily depressed all the same.

It's all a matter of personal perspective.
