A female who's entire world revolves around sex. Not to be confused with a sex addict who cannot control their sexual escapades. The nympho can choose her partners and how far she is willing to go. It often causes problems in serious relationships. Nymphomaniacs are not whores. Some have been with many men, some with one man, and some are still virgin. Nymphoism is more a state of mind than anything else.
She is a nymphomaniac because she thinks of what she is going to do to you all day long!
