Being Transsexual is Like ...

[Sandy]

Perhaps someone who knows latin could come up with something that means "appearance mismatched with identity" or something...

That would be:
vultus mismatched per identity

(I love the internet...)

Not very satisfying, but there it is...

mismatched didn't translate

I fiddled with a translation machine and got "Appearance differs from identity" =  "vultus distinctus ex identity"  or "appearance different from identity" = "vultus diversus ex identity"

[Tammy Hope]

Appearance differs = Vultus distinctus, eh?

Interesting for a motto perhaps but unwieldy...

So much for that idea lol.

I haven't found an English to Latin translator to experiment with.

There are surely some words that would produce a smoother label but latin might not be the right root language to use

nefas pars sicco puella - wrong side out girl

It's what I used.  I don't think it has all the latin nuances though.
