Hiya Noah,
Really lady? You look hot. Change your name to Sputnik and you'll still look hot.
I have 3 [count 'em, 3] non-trans girlfriends named Michael... and none of them are half as cute as you are. I have a friend named Franky (she's pretty damn cute!) And I use to work with a cutey named Jeff. Maybe it's a side effect of having grown up in the Encino area of Los Angeles (I grew up in an area where lots of entertainment industry folks were raising their kids.)
If I were in your cute shoes, and I really wanted to keep the name Noah, I would do just that, and tell people that they can call you Noey if it makes them more comfortable, or something equally playful. Heck, my legal name is Kathryn, but most people call me Katie, except a lot of my friends call me Miharu, and my spouse calls me Mimi. Just have fun and do with your name what feels like fun. If you're having fun with it, people will pick up on your fun and they'll have fun too. And they'll still be thinking to themselves, "Damn, she's hot!"
Well, that's my 2 cents anyway.
Hugs!
Miharu
