Did I tell you I feel like a child because, at 31 year of age, I can't grow a beard?
That's not a big deal one way or the other.
But what would people think of me if they knew I couldn't grow a beard?
You shouldn't cave into social pressure to grow a beard. Fashion and looks change all the time. You should focus on the things that you can change.
I don't think you understand how people judge effeminate men.
What makes you a man goes far beyond how fast or heavy your beard grows. You're under no obligation to conform to anyone's narrow and outdated ideas about what makes a man.
