Never thought of that. Nice observations there. Indeed, it's a shame that there aren't female logia users. Actually, this reminded me of something:

In the Japanese folklore there's a female spirit called Yuki-onna. Like the name suggests, she is associated with winter, snowstorms, freezing to death and so on. So, if a woman ate the Hie Hie no Mi instead of Aokiji she would most likely have been associated with a Yuki-onna. Logia and feminine at the same time :D
