Le Guin on The Left Hand

"With twenty years of feminism under my belt, I can now imagine an androgynous society as being much different and far more interesting than our gendered society. For instance, I wouldn't lock the people from the planet Gethen, where the story takes place, into heterosexuality. The insistence that sexual partners must be of the opposite sex is naive. It never occurred to me to explore their homosexual practices, and I regret the implication that sexuality has to be heterosexuality."
(in an interview with Jonathan White, 1994)
