When I was a little girl, one of the main things orientated towards girls was princesses: the whole vibe of dressing up with sparkly dresses, tiaras, makeup etc so you're super cute when the brave prince comes to rescue you from the ugly witch or wizard and all their monsters
Yet being the "prince" was never a role heavily orientated or encouraged in boys.
It seems weird to me because a prince seems to pair perfectly with the "princess" role for girls, and is also very typically boyish and action orientated: defeating the villains, rescuing the beautiful princess. Instead boys were moreso pushed towards ninjas and pirates and knights.
Do little boys just in general not like the idea of being princes?
As a kid I loved to imagine being a princess and getting rescued by a prince!
