Hey Pandas, How Did You Know You Were/Are Part Of The Lgbtq+ Community

I accidentally found my grandpa’s playboy magazine as a child and thought about it until I was old enough to know why I was thinking about it

We had a sub in class and I was hiding in a closet trying to scare people but I had some tone to thingy about life and all that and when I came out I was like "oh"
"I'm gay"

Mine was a combination of reading "The Miseducation of Cameron Post" and getting a massive fifteen year old crush on my best friend.
