NYMPHOMANIA:
When the word "nymphomania" was still used, it only applied to women. In Greek mythology, "nymph" was the name of little spirits—who coincidentally always resembled beautiful young women—hiding in nature. "Mania," meanwhile, refers to excitement and excessive enthusiasm.
So, in short, the word literally translates to: "excessively excited spirit." True hypersexuality isn't just about really (really) loving sex; it's characterized by invasive thoughts, fantasies and urges that operate at an intense level. Before diagnosing, signs must persist for a minimum of six months. These feelings are strong enough to interrupt the person's life and to make work, friendships and other relationships difficult, due to things like cheating, obsessive attachment, pornography addiction and other actions not generally conducive to healthy partnerships.
