Speaking to MTV News, Watson revealed that their gender journey began around the age of 13, when they "felt a little queer" and they weren't "really sure what to do with that." But recognising an attraction to girls, they therefore began to identify as a cisgender lesbian.
They later revealed that stage lasted about a year and a half before they realised that the label wasn't quite a perfect fit. "It wasn't quite encapsulating the pain that I was really feeling. There was something body-related, there was something else there, and all I had to label that under was being trans," they shared, which led him to them identifying as transgender instead.
Then when the time came for them to begin transitioning, they realised it wasn't a step in the right direction. Watson realised that transitioning to male felt just as wrong as growing breasts. "I realised in doing that that the problem wasn't that I wasn't male, the problem was just that I was female," they said. And that's when they began to identify as nonbinary.
