"Is the gender you identify with the same as your sex registered at birth?"
The thing with this is that I don't actually know how I would translate this in the second/third languages in my family. There's not really commonly-used separate words for sex and gender in this way.
The only way to really ask it would be to say something like "do you disguise your birth type for social reasons?" But even then, social has overtones of tribe and community, and you bring other cultural phenomenon into play where very definite females have historically done male activities (like riding into battle) and this has been seen as disguising from the enemy her birth type, but not that she's actually male in any way.
The problem is the words used. Gender is obvious, as is sex, but "identify" is very easily translated as "recognise a person, place or thing" whereas in English now, identify means something more like adopt or 'believe oneself to be".
"registered" is also difficult. It can have very distinct document overtones, particularly in terms of property and ownership.
So I can see how this question could be mangled to say something like: "are the words you use to recognise things different to having sex to make babies?"
