"Another characteristic of contemporary utopias is sexual permissiveness. The point of that permissiveness is not to break taboos but to separate sexuality from questions of ownership, reproduction and social structure. The feminist utopias that are not entirely lesbian often assume, as in Ursula Le Guin's The Dispossessed, some mix of monogamy, casual promiscuity, homosexuality and heterosexuality, with adolescent bisexuality as the norm."
