Guy Hocquenghem, essayist and activist, is often considered the father of Queer theory. He was the author of Homosexual Desire (1972) and L'Amour en relief (1982). The Screwball Asses is his first work available from Semiotext(e).
One of my favorites! The main character meets a girl who has similar features, but mirrored. I have a Dutch version, also one of the book I'll not rent out. The book is from 1987.
