 In your heart and in your head, just like the language that we used when they were younger. But it's something personal. It's something that's unique to you. It's something that you get to decide. Gender expression is what you share with the world. How you dress, how you act, what you're interested in, what you put out there. And that, again, is your choice. It's something that you can change from day to day. It's completely up to you. Sexual orientation is who you are emotionally and physically attracted to.
