Yes, you'll find that every dominant has their own needs and requirments, so no matter how much or how little experience you have, you will be striving to meet your dom/me's needs.

And dominants are far more tolerant of inexperienced subs than the other way around. There's a joy to be had in the training.

Regardless, and imo, very few "first" relationships survive because the less experienced partner is figuring out what they want. So to that end, I'm sure your domme is more worried about disappointing you than you are of disappointing her at this point.
