Kicking Butt Knows No Gender

I am genderfluid, but I was assigned female at birth. I am on the wrestling team, and we have to wear jackets on the days of meets. 

Girl: “Oh, it’s so cute that your boyfriend gave that to you!”

Girl: “No! it has to be your boyfriend’s!”

Me: “[Girl]… Um… I’m gay.”

Girl: “So? What does that have to do with this?”
