You're young.
Learn it now, accept it, embrace it, and enjoy it. Women are submissives, and men are doms.
Yeah, there is more responsibility on the dom as standard. Easy way deal with that is by making some limits on your time. Quality over quantity.
She's giving you all the power, and she wants you to take it. It might not seem like that at first. When you are starting from scratch (IE, no current plates), then initiation can seem like a burden. It's like being at the bottom of a mountain looking up. But when you start pushing things, spinning-plates and having many good relationships, you will have a different perspective from the top of the mountain. Which is that initiation is a great privilege. Your fate is in your own hands.
As long as she's following your lead, all is good. There's no problem to solve, just androgynous whining.
