Erotica

Erotica is art, literature or photography that deals substantively with subject matter that is erotic, sexually stimulating or sexually arousing. Some critics regard pornography as a type of erotica, but many consider it to be different. Erotic art may use any artistic form to depict erotic content, including painting, sculpture, drama, film or music. Erotic literature and erotic photography have become genres in their own right. Erotica also exists in a number of subgenres including gay, lesbian, women's, monster, tentacle erotica and bondage erotica.

Curiosa are curiosities or rarities, especially unusual or erotic books. In the antiquarian book trade, pornographic works are often listed under "curiosa", "erotica" or "facetiae".

The term erotica is derived from the feminine form of the ancient Greek adjective: ἐρωτικός (erōtikós), from ἔρως (érōs)—words used to indicate lust, and sexual love.

A distinction is often made between erotica and pornography, although some viewers may not distinguish between them. A key distinction, some have argued, is that pornography's objective is the graphic depiction of sexually explicit scenes. At the same time, erotica "seeks to tell a story that involves sexual themes" that include a more plausible depiction of human sexuality than in pornography. Additionally, works considered degrading or exploitative tend to be classified by those who see them as such, as "porn" rather than as "erotica" and consequently, pornography is often described as exploitative or degrading.

Erotica exists in many different forms, both modern and ancient. Erotic art dates back to the Paleolithic times, with cave paintings and carvings of female genitalia being a point of immense interest to prehistorians. Ancient Greek and Roman art depicted erotic acts or figures, often using phallic or erotic imagery to convey ideas of fertility. Modern depictions of erotic art are often intertwined with erotic photography, including boudoir photography, and erotic film. Discussions of modern erotic art are also often merged with discussions on pornography. More specifically, erotic photography found its mass-market roots in pornographic magazines. The most iconic of these magazines is Playboy, a men's magazine founded in the 1950s that helped to shape the modern Western perception on sex and sexuality in the media. Pornographic magazines could also include boudoir photography or pin-up models, though pin-up models are not definitively sexual by nature.

Erotic film has evolved greatly with modern filmmaking capabilities, including developing a large subgenre of cartoon pornography, the most popular form of which is Japanese hentai. Erotic film is the form of erotica most often seen as interchangeable with pornography due to their similarities in form and function.

Erotic literature also dates back to ancient times, though not quite as far. Arguably the most iconic erotic piece of literature, the Kama Sutra is a Sanskrit text largely describing and depicting ideas of sex, sexuality, love, and human emotion. Eroticism in ancient Greece and Rome was not contained to only visual art, as poets such as the Greek Sappho and the Roman Catullus and Ovid wrote erotic verse and lyrical poems. Modern erotic literature, often called 'smut', is quite popular, especially among women. In the 21st century, fan fiction erotica has gained popularity. Stories on online websites like Archive of Our Own and FanFiction.Net account for a large percentage of modern erotic fan fiction literature. A large sample size revealed that women read more erotic literature than men, and that among those who consistently read erotica, about 95% are women.

The topic of sex is often taboo in modern culture, especially in media. Censorship is an issue often faced by creators of erotic work, be it art, film, or literature. The legality of creating and publishing erotic works differs in different parts of the world, but it is not uncommon to see heavy regulations placed on the publication of erotic or pornographic media.
