My name is Erin, I'm male, not female. I get mail addressed to Ms. Erin .... All the time. People commonly assume my name is spelled Aaron, or call me Eric when they see the spelling of my name. I once deployed to Saudi and when I got there, they had to give me a new dorm room, because they placed me in the female dorm.
To be honest, I don't even care. Got bigger things to worry about then people getting my name wrong.
