Asexual

Today’s topic comes from QSFer Elizabeth Barrette: Asexuality in spec-fic. Asexuality doesn’t get talked about much – many folks have dismissed it, in fact, as it doesn’t seem to make sense to them. After all, the thinking goes, who wouldn’t want to have sex? On the other hand, the idea of homosexuality has long been discounted because straight people couldn’t envision it for themselves. So my questions today – how would you define asexuality? As a writer, have you included any asexual characters? As a reader, have any of the books you read included them?
