Try being Kim a little more often, without saying anything.
Do not bring up the subject of transitioning or being more feminine than what she desires at the moment.
Regulate your dressing to please her and it will all appear natural.
I for instance can now go outside or home and drive tho the shopping centre without a comment being passed.
I make no comment like "Do you mind ?" or anything like that.
Just do it naturally.
If she starts to get cld feet again you can easily back off to suit the mood.
Do not push the boundaries, one day she may like you to have real boobs, then do something about it.
In the meantime there is a lot of living to do and you have been given an opportunity to express yourself.
As Ru Paul would say, "Don't fluff it up"
