My mother said I look like a girl now!

2 days ago I shaved my legs and I LOVED IT. However, that’s not the case. The day after I shaved, I showed my legs to my mother, even though I haven't come out to her yet. Whit a big grin she said, "You look like a girl now." I'm so happy right now! Do you have any advice on how to take the next step and tell her that I feel like a girl?
