Erotographomania is a strong interest or desire to write erotic or romantic literature to achieve sexual arousal and pleasure. This strong interest is more than simply a taste for erotic or romantic literature, and may even be termed an obsession.
Erotographomania is a sub-variant of condition graphomania, which is the need to write excessively. While graphomania does not necessarily imply erotic writing, in some cases it can.
