When did you find out you were nonbinary?

Hey everyone, new to the subreddit and wanted to ask, when did you find out you were nonbinary?

I myself just started trying on they/them pronouns with my close friends after having been question for roughly a year now.

I ask because I never want to feel like I'm taking up space in a place that isn't my own, and being disrespectful to others who are more rooted / secure in their identity.

I will say, while I'm still new, I feel super cozy. I wouldn't say there was an "a-ha" or "click," but rather. It just felt nice.

It's comfy, cozy not having to feel the pressures of manhood on me. Lol.
