    Kate Bornstein mentioned gender fluidity in 1994, in the book Gender Outlaw: On Men, Women and the Rest of Us, "and then I found that gender can have fluidity, which is quite different from ambiguity. If ambiguity is a refusal to fall within a prescribed gender code, then fluidity is the refusal to remain one gender or another. Gender fluidity is the ability to freely and knowingly become one or many of a limitless number of genders, for any length of time, at any rate of change. Gender fluidity recognizes no borders or rules of gender."[1]
