Is part D referring to which gender you present yourself as?

Yes

On the last, I think I need clarification as well.

Sorry, my fault. I should have called it "gender expression" which is how we present our selves to the world in terms of expression, behaviors, interests, affinities, etc. It's also how the world sees us, and/or how we want the world to see us -- male, female, or a combination.

My gender expression is that of a man. I don't think I've ever been mistaken for a woman. e.g., a store clerk calling me "Ma'am". I make no attempt to present as female in public. At home I'm experimenting with doing so (but with varying success).
