"The world can't afford sex anymore." "Of course it can afford sex," said Billy. "All it can't afford anymore is reproduction." "Then why the laws?" "They're bad laws," said Billy. "If you go back through history, you'll find that the people who have been most eager to rule, to make the laws, to enforce the laws and to tell everybody exactly how God Almighty wants things here on earth—those people have forgiven themselves and their friends for anything and everything. But they have been absolutely disgusted and terrified by the natural sexuality of common men and women."
