Dude you are describing a drone, LOL....
i.e. totally capable and independent and highly skilled etc but happily plays the supporting "man" or team subordinate.
That is hardly fair to any live flesh and blood woman
If she's got all those contrasting traits, and good on her, then she's allowed to have her own mind and her own opinions and to disagree. And to slot you into the supporting role equally, in every way that counts. That's what the balls and backbone are for, else it's a waste of good steel ;)
Let me ask you this...if her figurative pair is probably bigger than yours and she decides a true partnership in her view might differ from the role you see her in, would you still be good with that? What is she is the stronger one, aside from physical strength, and she simply wants to relax and let her pair hang free? Do you still need her to be sweet and fun, or is it ok if she is just real, authentic, sincere, caring, deep, etc., and yes, STRONG...whilst also being even-tempered, smart, etc?
Is that ok and are you good seeing and describing her in those terms? As she is at core, all physical appearances/vulnerabilities aside...or is that not quite the place you had in mind for her? Just asking as I'm not saying I know one way or the other what you'll say.
What I mean is, you can describe a person and who they are in many ways...and IMO the truest ones are the most universal...they are those qualities which you could and would immediately also apply to yourself. And which you would readily choose and prefer to have others use to describe you. Would you classify your own lighter side as sweet and fun and curvy, or would you perhaps say more like "strong but kind, discerning and caring, and [you'd leave curvy off, right?]"...etc.?
Just some food for thought...
Peace & blessings
