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 them to be separate. 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 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". (Full article...)

Pornography (colloquially called porn, or porno) is sexually suggestive material, such as pictures, videos, text, or audio intended for sexual arousal. Over the course of human history, pornographic depictions have taken many forms, from stone carvings in the Upper Paleolithic, to virtual reality experiences in the present day. It is almost always made for consumption by adults. A distinction is often made between pornography and erotica, although some viewers may not distinguish between them.

Human fascination with sexual imagery has been a constant throughout history. The oldest artifacts considered pornographic were discovered in Germany in 2008 and are dated to be at least 35,000 years old. However, the reception of such imagery has varied hugely by cultural context. The Indian Sanskrit text Kama Sutra (3rd century CE) contained prose, poetry, and illustrations regarding sexual behavior, and the book was celebrated; while the British English text Fanny Hill (1748), considered "the first original English prose pornography," has been one of the most prosecuted and banned books. In 1896, a film by Thomas Edison that depicted a kiss was denounced as obscene in the United States, whereas Eugène Pirou's film Bedtime for the Bride from the same year was received very favorably in France. Starting from the mid-20th century, societal attitudes towards sexuality became more lenient in the Western world where legal definitions of obscenity were made limited. In 1969, Blue Movie by Andy Warhol became the first film to depict unsimulated sex that received a wide theatrical release in the United States. This was followed by the "Golden Age of Porn" (1969–1984). The introduction of home video and the World Wide Web in the late 20th century led to global growth in the pornography business. Beginning in the 21st century, greater access to the Internet and affordable smartphones made pornography more mainstream. (Full article...)
