Sean Carroll in Preposterous Universe:
Sexuality is, and always has been, a topic that is endlessly fascinating but also contentious. You might think that asexuality would be more straightforward, but you’d be wrong. Asexual people, or “aces,” haven’t been front and center in the public discussion of gender and sexuality, and as a result there is confusion about such basic issues as what “asexuality” even means. Angela Chen is a science journalist and an ace herself, and she’s written a new book about asexuality and how it fits into the wider discussion of sex and gender. Precisely because sexuality is so taken for granted by many people, thinking about asexuality not only helps us understand the issues confronting aces, but the meaning of sexuality more broadly.
