"The key element here isn't whether the composition of the face or figure is anatomically correct, or whether the art object's style is realistic, impressionistic, expressionistic, or anything else. If the work has been executed erotically, it's generally assumed that the creator viewed the subject matter as praiseworthy. Something to take pleasure in, celebrate, exalt, glorify. . . . And in this sense, the erotic and the aesthetic merge.
There's substantially more overlap between the aesthetic and the erotic than the erotic and the pornographic. Unquestionably, erotica and pornography both present the human organism in a manner that's sexually compelling. But the aim of the pornographer is hardly to help his or her (most likely his) audience rejoice in the human form--or in some way honor physical intimacy, or the joys of the flesh. Rather, the objective (typically leaving little or nothing to the imagination) is to "turn on" the viewer."
