Unsatisfied Switch

My bf has introduced a few kinks I'm very down with, though I don't want to be submissive as often as he wants to be dominant- I wish we would devote some time to a couple kinks of mine he's less enthusiastic about, or outright refuses.

I understand that not everybody is into everuthing, but it makes me feel disappointed and lonely, and like things are unbalanced. Does anyone have advice for helping me help him go from "willing to try" to "LET'S GO" when it comes to female domination, or advice about helping me let go of the fantasies he can't get behind? I'm set on staying monogamous, and I don't like this feeling.
