Is there a feminine equivalent for 'Casanova' without negative connotations?.

I don't think you can find a term that is entirely symmetrical, because the cultural concepts of romantic and sexual pursuit aren't symmetrical. Identical behavior in a man and a woman will usually be interpreted differently in most cultures I know. The reason it's hard for you to find a non-perjorative female counterpart to casanova, and the reason so many of the suggestions given here are either negative in connotations (maneater, siren) or full of other connotations (Mata Hari, Cleopatra) isn't in the words and names, they just reflect a cultural bias inherent in our society.
