The fact that there’s not an easily defined name for it should tell you something.
The long and short of it is that emasculation is what happens when people think someone isn’t acting enough like “a man,” or is stopping someone from doing so.
In women, it’s generally acting too much like a man. Getting called “shrill” or “aggressive” is something that frequently brought against women who take an assertive role. I’ve also seen women who were in senior positions asked to take notes during a meeting, as if they were a personal assistant rather than a manager.
Emasculation is treating a man as less than a man. As if he were a woman. The equivalent for a woman is treating her like society has traditionally treated a woman. Our current best word for that is probably “misogyny,” but we can unfortunately also go with “normal.”
Wings evolve from legs though, generally speaking. This means that a four legged dragon with wings would have conceivably evolved from a six legged creature. You can get hand-wings or arm-wings, and we’re not entirely sure but think insect wings may have also evolved from legs or some other kind of similar structure.
But pretty much you can either have wings or legs/arms. You have to trade them in. That’s why the whole angel/demon thing doesn’t work either. The traditional harpies work but they’d be furry and not feathered. I haven’t worked out the wingspan for them but you could probably come up with a reasonable guess. They’d be more bat-people than bird-people, and I suspect that their chest areas would be less generously proportioned than is typically seen in the artwork. I’m not going more into the physics of that one though.
