Ok, so I was watching Jurassic park and the answer to my question about air nomad women appeared... it;s really easy... the air nomads are a-sexual like some frogs! Think about it, look at them sitting like frogs on lilly-pads when Aang and Gyatso throw the pies at them!... but now that I think about it... to be a-sexual, you have to be female... another theory gone... anyone else?
