Nymphomaniac

Hypersexuality is a clinical diagnosis used by mental healthcare researchers and providers to describe extremely frequent or suddenly increased sexual urges or sexual activity. The terms nymphomania and satyriasis were once used to describe the condition, in women and men respectively, but are no longer in general medical use, although the former is still used colloquially.

The Merriam-Webster Dictionary defines hypersexual as "exhibiting unusual or excessive concern with or indulgence in sexual activity".Sexologists have been using the term hypersexuality since the late 1800s, when Krafft-Ebing described several cases of extreme sexual behaviours in his seminal 1886 book, Psychopathia Sexualis. The author used the term "hypersexuality" to describe conditions that would now be termed premature ejaculation. Terms to describe males with the condition include donjuanist,satyromaniac and satyriasist, for women nymphomaniac, while hypersexualist is a gender neutral term.

Hypersexuality may be a primary condition, or the symptom of another medical disease or condition, for example Klüver-Bucy syndrome or bipolar disorder. Hypersexuality may also present as a side effect of medication such as drugs used to treat Parkinson's disease, or through the administering of hormones such as testosterone and estrogen during hormone therapy. Clinicians have yet to reach a consensus over how best to describe hypersexuality as a primary condition, or to determine the appropriateness of describing such behaviors and impulses as a separate pathology.
