Yeah, I basically agree. I think that might be the spiritual separation of the pornographic and the erotic. Erotic can be transcendent, it can be a distillation of sexual beauty. The Venus de Medici is erotic, for example. “The Song of Songs” is arguably erotic. 

Pornography is the equivalent of just eating a bowl of sugar. Yeah, it tastes good because your brain associates sweetness with fruit. But it’s not fruit, it’s a false representation, and you’ll get sick sooner or later if you eat enough of it.
