Going back to Windhover's point, it's only really in English that there's such confusion between sex and gender, after all when English had grammatical gender, "woman" (wife-man) was masculine. That's what led to Sammuel Clements pronouncing that Germans had no sense of humour because they didn't find one of his pieces funny, as it was based on the premise that German grammatical gender if transliterated into English is absurd.
