I wanted to, sort of, but I sort of had already chosen my name before I mustered the courage to come out to her, so I waited for a bit. At some point, I asked her to choose my middle name (because I was past the point of no return in the choice of name), and she declined, saying I didn't need a middle name.
A few months later, she asked me if I could change my name, because she didn't quite like it. She said she really liked names that fit both boys and girls, like my sister's name. For one, it was way too late to say it at that point. And, well, when what you fear the most is to be taken for a guy once transition is done, picking a name that might give someone an impression that you're a guy is probably not the best idea. So I'm sort of happy I didn't have her choose my name, because of her tastes.
