An excessive or obsessive preoccupation with sexual matters, desire, or erotic pursuits; pathological sexual obsession.
From erotic + -mania (Greek mania 'madness, excessive desire'). This medical/psychological term emerged in 19th-century psychiatric literature to describe pathological sexual preoccupation.
Eroticomania is what old psychiatrists called being obsessed with sex to the point of dysfunction—it's one of those Victorian medical terms that sounds funny now but represented serious attempts to understand why some people's desires became overwhelming and destructive.
