Ok, so if you are talking about right now as an addict NO there isn't any difference, if you are talking about being adolescent looking at a playboy mag versus a porn video YES.
But right now, and unfortunately I'm an expert on this shit. It's whatever gets you off, it doesn't matter, plain and simple. I've often mo to images rather than videos because I couldn't find what I was "searching for." I've grown to understand the concept that it's whatever is giving you that dopamine kick is what you must eliminate. Images, videos, staring at women public throwing that image in the spankbank. It's all garbage.
