I've been in back to back relationships since I was in middle school—sixth grade, to be exact. And before you start thinking that they weren't real because I was so young, remember that those younger than you are people, too.
I haven't always known I was gay or gender non-conforming. I used to be cishet. But the first time I remember my gayness coming out is when I was a young child.
I've always been told I'm weird, ever since elementary school. I'd get bullied for it, but I didn't understand why. Now I do, and I've decided to embrace it. I guess it's a lot more acceptable in adulthood.
