Erotica, from the Greek eros, love, is art (including literature, photography, painting, etc.) intended to stimulate or arouse sexual love or desire, by virtue of the fact that it deals in unambiguous portrayal of sexual acts or situations.
In contrast to pornography, the term "erotica" is usually associated with aesthetic and artistic treatment of its subject matter, as opposed to raw sexuality without artistic overtones. Pornography is popularly focused on unadorned lust, sexual acts and sensations, while erotica generally tends to include higher emotional content, the development of place, character and story line, or of an overall artistic theme. However, such distinctions are necessarily subjective and may say more about the critic's own tastes on erotic material than the artistic and other attributes of the material itself.
It has been said that "The difference between erotica and pornography is simple. Erotica is what I like. Pornography is what you like, you pervert!".
It is a notable trait of the strength of the human reproductive drive relative to the psyche as a whole, that unambiguous reference to sexuality, framed in a manner which the perceiver thereof finds acceptable, tends to intiate an involuntary reaction of sexual arousal, possibly building increased sexual desire, which may lead to creating or taking advantage of opportunity to engage in sexual activity. This can be true of erotica just as well as other, both more and less refined references to sex. Depictions of the human body which merely fail to conceal or disguise the secondary sexual characteristics of its particular gender may be all that is necessary to trigger arousal in a person who is attracted to that gender. For this reason, erotica is too broadly described merely in terms of the effect that it engenders in its audience, as all sexually related matter has the potential to create such an effect.
