Many non-bisexual people think of bisexuality as a split experience of the self. They think of a bisexual as sometimes gay or lesbian (with a side serve of heterosexism) and sometimes straight (with a side serve of heterosexual privilege) by turns. They imagine her sense of herself is split into two pieces. Sometimes she plays for one team, and sometimes on the other. [...]
But the life writings of bisexual people do not reflect this picture of an unavoidably fractured identity. Bisexual people often experience the decision to adopt identity as naming the entirety of their experience as a unified whole. Many of us experience choosing bisexual identity as a homecoming. It allows us to name feelings, experiences, and self-understandings as part of a whole, rather than demanding that we attempt to understand ourselves or explain ourselves to others as sometimes one thing and sometimes another. In a sense, it is a choice in the direction of unification, exactly the opposite of being split.
