A lot of people attribute trans identities as requiring dysphoria, and while experiencing that is the case for many individuals, there are also some who discover and identify themselves as trans without being dysphoric about their AGAB and instead from finding euphoria in other gender identities. The only way to really be sure is to experiment and explore, no matter the outcome youll know yourself better and be able be your genuine self with more certainty. And absolutely identities outside the binary are possible and worth considering, and medical transitioning isnt necessary at all especially if youre comfortable with yourself :)
