I'm 5'5", built like a 6'5" tank of a man, just shorter. I would kind of like to be taller, but I'm mostly fine with it. Most cis men in my area are shorter than me. We are a very short people in West Virginia. If you see a man taller than 5'7", chances are they're not from this area. I have a cis guy friend who's 5'1" and is a tiny little thing. He's totally secure and doesn't think twice about it, and he's well liked and popular. So yeah, confidence is key.
