Yes pretty much in most cases it is an issue which people have to arbitrarily have to define. I just know that sometimes at least to my mind that some forms of pornography depict and show things in such a way that it distorts the natural desire or instinct of the individual person. Things with a sexual context have the potential to be good and fruitful its just how its depicted, the way we interpret it, and what our final intent is in the course of engaging with it.
