Jo Walton said this quote

On the one hand, Gramma and Grampar never mentioned sex at all. They must have done it, or they wouldn’t have had Auntie Teg and my mother, but I don’t think they did it more than twice. Then there’s the way they talk about sex in school and in church. And there’s no sex, hardly any love stuff at all, in Middle Earth, which always made me think yes, the world would be better off without it.
