So, I moved to Colorado last August, and I knew I liked girls. At my last school, I was very hush hush about it. When we moved, I swore that I would be more open about my sexuality, like one of those typical out and proud high school girls. Then I realized something. I have no idea how to do that. When I got here, I found myself ignoring several chances to make my sexuality a more well known topic. I don't want to go around saying, "Hi, I'm a lesbian" to people, but I don't want them to assume I am straight when I meet them. I've always looked pretty normal. I'm not extremely butch, and I'm not extremely feminine either. I don't wear makeup, skirts, dresses, or any type of sandals to school. Strictly combat boots or Converse. I have long hair, but want to cut it short. Basically I am saying, how the hell do I tell people I have just met, or that I have known for a few months that I am a lesbian?
I've kind of done that already. I regularly wear spiked earrings with the gay flag colors, and a studded leather bracelet that is also rainbow. For awhile I had a keychain on my schoolbag that I sewed with the gay flag, and put the word PRIDE underneath.
I'd keep doing that. People probably assume things because of it already, but maybe don't say it to your face for whatever reason. When they ask or you hear a comment, you can just say that it's true that you are a lesbian. You could also make comments about hot girls to friends or talk about current LGBT+ topics. Just make sure it's not the only thing you talk about because lesbian is your sexual orientation, not your personality.
If your school has a GSA, I'd advise joining it. Make sure you come out to your friends, and don't be shy about telling people when you see a cute girl. If you want, you could also get some people to start spreading it around the school.
I second that. Holding hands with your girlfriend while walking through the halls screams lesbian. Kissing on her during lunch is also a give away. (!)
