I'm not trying to disavow our most basic impulses, but there's so much more to erotic art than "gross anatomy". And I don't mean you have to cover up and be coy. You can show the anatomy. But there are more parts of the human body that are attractive than just the genitals. And there are ways to frame the genitals, to groom them to be more presentable.
Although it has been documented that arousal suppresses our disgust reaction to some degree (why else would anybody want to lick another person's anus?), aesthetics don't go out the window just because our sex drives are engaged. It's about more than just looking at unkempt body parts that are normally hidden from our view. There's a psychology that goes into what we find alluring; a way to stimulate our bodies and minds simultaneously, for a more intense and lingering reaction. That's what erotic art attempts to evoke. It doesn't always succeed. After all, there is a heavily subjective element involved. But isn't it worth the try?
Some people want to keep their dirty magazines separate from the paintings hanging on their wall. Isn't it the very concept of "pin-ups" to merge the two? There's a delicate balance to be achieved in creating a portrait that can stir the loins, while also possessing enough taste and class to warrant hanging above the fireplace. Some say it can't be done. But it makes for a thrilling artistic challenge.
