The trope of Pandora's box was already associated with the female body in the previous decade, in Jonathan Swift's "The Lady's Dressing Room", and "A Secret History" proposes that the female parts "may well have been the original Pandora's box".  The connection is found in subsequent erotic fiction as well.
