Transmasc and nb here too! I've been on t for 6 years now, and I have like. A progressive list of identities I disclose based on how much the person I'm talking to understands about trans stuff:

- trans man (what I usually use for cis people if I need to talk about it)

- nonbinary

- polygender

- kuiperian (final boss, made from the galactian gender system)
