How do I know I’m nonbinary? Well the truth is I don’t. All I know for sure is that I’m not a man. I tried to fit that role for 26 years and I have plenty of experience to show me that it didn’t work for me. I tried being a masculine man, I tried being a gender non-conforming man, I tried being a sensitive man, I tried being an emotionless man. And it just doesn’t fit. So am I a woman or am I nonbinary? I don’t really know but what I do know is that binary gender expectations and the idea of “opposite sexes” harms all of us regardless of how we identify so I’m perfectly content to fight for nonbinary representation even if that’s not where I end up someday.
If you’re trying to figure out if you’re nonbinary, I recommend starting with Sam Dylan Finch’s articles on Everyday Feminism like Help! I Think I Might Be Non-Binary, But How Can I Know?
