Adults tend to treat boys and girls differently from very early on, but the infant’s bisexuality precedes its own subjective experience of gender. The meaning of gender distinction only comes into focus when an unwelcome new baby arrives – or when the infant fears that it will, as it might have seen happen, say, to its friend – and is either the same or a different sex. Thereafter bisexuality as a subject position, like the feeling of ambivalence, is experienced only fleetingly, as two genders present at the same time. A girl who knows and feels she is a girl experiences herself at the same time as a boy, and vice versa. And, as with ambivalence (but in the case of bisexuality, only after infancy), the complete simultaneity cannot be sustained. The psychic pendulum swings from one to the other, or one dimension remains hidden and subjugated to the other. Because, at one time, we were happily bisexual, this is a both/and, not an either/or position... the dominant mode will shift according to context, or one’s stage of life.
