I know that the names we use are a large part of our identity. And many of us choose to change our names when we transition and/or when we begin presenting ourselves differently.
I present as male in day-to-day life, goal one is to add elements of feminine presentation so my day-to-day becomes more androgynous/bit-of-both. Goal 1.5 is I want to feel able to present as female on a given day if I so chose, I've got a fair bit of social practice to get there.
My SO is WAY more comfortable in public with gender and sexuality than I am and it always grates on me when they have drawn attention to it, even if we're just walking through the mall talking amongst ourselves and I know that no-one is really listening. (It still seems like they're yelling at the top of their lungs. "OOH THAT BRA WOULD LOOK CUTE ON YOU!!!"

*sigh*)
I've been blessed with a name that has some form in each gender. (IE: Chris = Christopher/Christine, Rob = Robert/Robin, Jess = Jessica/Jessie, Aaron/Erin). I've discussed with my SO about using the feminine counterpart to my male name in public, 1) when referring to the feminine aspect of my gender ("How do you think X will look in this" instead of "How do you think you'll look in this...") and 2) if I was ever to go out in public as female (theoretically, at least).
I found it helps to relieve a lot of the social stress I feel to disassociate it a little.
I feel a little like I'm short changing myself on an opportunity here, but also I feel like this fits me best because, in my head both the feminine aspect and the masculine aspect are parts of the whole "me".
