Female led relationships discussion

My girlfriend and I are newcomers to the D/s dynamic. While I was the one who pulled us into this lifestyle, she is genuinely excited about it as well. She tends toward vanilla but enjoys the concept of power dynamics. We are both putting in effort to get used to our new roles: I am learning to leave my ego at the door, while she is practicing being more self-centered and honestly asking for what she desires. I no longer worry so much about my own satisfaction; instead, I have dedicated myself to her pleasure, which has worked out wonderfully. She really appreciates the oral focus I give her, along with me preparing her meals and maintaining a clean home.

I am curious if there are other things I can do or any advice you might offer to help her grow into her role as Mistress smoothly? My goal is to support her blossoming into that title just as easily as possible.
