I got to ask, but how many men in real life do you know who are adults that are under 5ft tall? I'm honestly curious. I hate the dimorphism of the au'ra but here's something that folks aren't taking into consideration. It's not that the females are freakishly small, it's the fact the men are freakishly tall. The Au'ra women are what? 5ft maximum - may be a little smaller? I've seen plenty of women who are this height who are of age - 18 + etc; while the average height has them certainly higher - these women aren't huge outliners, plenty are this small.

Now, how many men do you know that are under 5ft who have gone through puberty? How common is it in society? Of those men who are under 5ft who have a childlike face, how many of those get constantly IDd because people assume they're underage?

I'm digressing; small women are commonplace. Small men, not so much sadly - and thus comes the whole idea that a man who is extremely small is seen as underage if his face shows anything that is somewhat boyish. Finally, it's the sad truth that small men are not pandered to - not unless the females are also small. Why? Because people tend to shy away from small men; it's why you don't tend to see them in a lot of media.

Again, having them be smaller than the females is fine - as long as the females aren't into the whole 'I don't date smaller men' trope. But to the point that they're a huge outliner at under 5ft? No.
