"You’ve got to understand they’re a puritan people, Commander. Sex is a very powerful taboo among Voorstoders. They delay it and forestall it when they can. The prophets of the Cause tell them sex is power, and being celibate stores up their power. The priests tell them married sex is all right, but only that. Both priests and prophets tell them not to look at women, not to think of women, that women are evil snares of the devil. And all women past puberty wear robes that cover all of them but their eyes."
