To be fair, the design of Corrin itself actually for the female moreso than the male.
Robin got by because their design is perfect for the Unisex look for each character and both designs I'm a fan of.
Female Corrin works in that design not out of sexualzation but by just of Male Corrin looking like a fuccboi in that design.
Plus I've seen people excuse

just due to how in the story, the actions are somehow justified because "women are emotional" and when

it just made him look incompetent.
That's what they said, not me
