[Morrigoon]

I think porn is defined by a combination of exposure and intent to titillate.

You can have exposure without intent to titillate, such as classical sculpture in a museum, whose purpose is to admire the human form, not inspire a stiffy.

Or you can have intent to titillate without exposure, such as the Song of Solomon.

But when you have both exposure (or graphic description) of body parts, AND intent to titillate, such as Playboy or the latest novel from Jude Devereaux, then I think that qualifies it as porn.

Speaking of which... I wish more boys read romance novels at an earlier age. It would sure clue them in on women a bit...
