Among the oldest surviving examples of erotic depictions are Paleolithic cave paintings and carvings, but many cultures have created erotic art. The ancient Greeks painted sexual scenes on their ceramics, many of them famous for being some of the earliest depictions of same-sex relations and pederasty, and there are numerous sexually explicit paintings on the walls of ruined Roman buildings in Pompeii. The Moche of Peru in South America are another ancient people that sculpted explicit scenes of sex into their pottery. .... Today, erotic artists thrive, although in some circles, much of the genre is still not as well accepted as the more standard genres of art such as portraiture and landscape. During the last few centuries, society has broadened its view of what can be considered as art and several new styles developed during the 19th century such as Impressionism and Realism. This has given today's artists a broad variety of genres from which to choose, including; fantasy, pinup, horror, fetish, comics, anime, hentai, and many other niche genres all with erotic elements. http://en.wikipedia.org/wiki/Erotic_art to the rest at Wikipedia
