Book excerpt: Using bisexuality as a frame, Go the Way Your Blood Beats questions the division of sexuality into straight and gay, in a timely exploration of the complex histories and psychologies of human desire. A challenge to the idea that sexuality can either ever be fully known or neatly categorised, it is a meditation on desire’s unknowability. Interwoven with anonymous addresses to past loves - the sex of whom remain obscure - the book demonstrates the universalism of desire, while at the same time the particularity of each individual act of desiring. Part essay, part memoir, part love letter, Go the Way Your Blood Beats asks us to see desire and sexuality as analogous with art - a mysterious, creative force, and one that remakes us in the act itself.
