I don't think 'sex' sells in terms of the outrageous number of female Miqo'tes at least. They... aren't... that... sexy. What they are is cute. Loli maybe. Cute and loli but not sexy unless you find those qualities sexy. Throwing cat ears and a tail on it doesn't sexualize it any more than handing me a kitten nestled in a pile of Victoria's Secret panties and telling me 'Get aroused'. Male Miqo'te? At least half of them are a different matter entirely.
Girls like cute things. Guy like cute things. Guys also like to trick other guys with cute things.
Result?
99% Miqo'te.
Also:
Not even the Amazons were all 'tomboyish'. Doesn't make no damn sense for Roegadyn men to be so manly and say to themselves "You know what I like? I like a woman who looks like a male Elezen. Bit more muscle on it. There we are."
Perhaps Roegadyn got saddled with the 'Female Night Elf' bag.
