Honestly, a big study in psychiatry is that with the appearance of the face and body, societies around the world judge haggard, masculine looks as "that person should not be playful, that freaks me out", all the way to how societies around the world view Androgynous all the way to Female images as "okay, that person looks soft, cuddly, or playful, that personality seems natural for them, I'm not freaked out."
With time, this can catch up to a naturally playful, cute acting person if the person develops very masculine, aged, manly features that don't suit the personality; it may not directly cause distress at first to the person, but eventual outside forces can. Trust me, both studies and personal experiences proves that almost every single person out there will be freaked out and even will make fun of a masculine man who acts cute, playful, "queer", or whatnot, when they wouldn't do that to a person who's appearance already "matches" with the playful personality.
This may and will cause an extroverted, playful, expressive person to become extremely introverted, shy, depressive, ect ect. There's rarely any escaping it, and it's a very extreme problem in the world of people who feel that they look different than what their personality is. It's why that, while a playful personality can truly be innate, that it is almost always diminshed as a person grows more haggard or aged looking. It's why many people are forced to "grow up", and the concept of "having to grow up just because I look grown up" is a horrid concept that I fight against a lot.
I just cringe when I see just how discriminatory society is against haggard looking men in terms of playfulness. It happens to me and it happens to other people. Yet it doesn't happen in the men who just seem to somehow not look old or haggard. It's like two different worlds!
