I've been secretly thinking of it as nb trans for a while, but I've not really said it to anyone aside from in this thread.
I like non-binary too, it's kinda like 'queer' (my other identifier of choice) because it covers all the bases and allows for freedom of movement within it.
If it comes up socially, I'll probably go with 'non-binary fem' as it's less likely to cause offence, and tbh I don't really want to be talking about my genitals to people.
If I ever get my dick though I'll probably be more comfortable using the trans label outwardly. Though I still have my little trans flag I embroidered on my jeans when things started getting bad here (UK) recently, so it might be assumed anyway by folk that see it I guess. And it definitely is if I'm unable to shave for a few days and stuck somewhere where I have to be seen by people (hospital is not fun).
