Wikipedia
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.
