A lot of why I use this messy graphite or ink sketch style is because it "resembles" old sketchbooks by the western masters from before Bridgman and before the standardization of art, similar to gritty ink work. Even if it's just porn, I want it to have that feeling that if you weren't looking at the subject, it was drawn by someone from before artistic teaching standardization. I don't know if I'll ever get there, but maybe in a decade I will.
