A big jawline is not a sign of high testosterone. Why is a big square jawline considered manly?
There seems to be a misunderstanding about feminine and masculine features for faces. I see people here saying that having big jaw, big chin is a masculine trait. There are plenty of low testosterone women with big square jaws: link
Big jaw is more representative of health (and growth hormone), not testosterone. Also chin is more about testosterone levels, not the jaw.
So why is a big square jawline considered manly?
What's Your Opinion?
