I was reading some old British texts and was struck by how euphemistically the writers refer to sex. It's always "laid with" or "spent a night" or in a lot of cases it's entirely skipped over and they just talk about some child that came out of nowhere. Online Etymology Dictionary says that "sex" referred the gender binary and is derived from "sexual intercourse," which was a euphemism that arrived in the 1700s. Was sex just conflated with marriage?
