Innate bisexuality is an idea introduced by Sigmund Freud. According to this theory, all humans are born bisexual in a very broad sense of the term, that of incorporating general aspects of both sexes. In Freud's view, this was true anatomically and therefore also psychologically, with sexual attraction to both sexes being one part of this psychological bisexuality. Freud believed that in the course of sexual development the masculine side would normally become dominant in men and the feminine side in women, but that as adults everyone still has desires derived from both the masculine and the feminine sides of their natures. Freud did not claim that everyone is bisexual in the sense of feeling the same level of sexual attraction to both genders.
