Can I be honest and say that this question makes my head hurt.
I know instinctively that I am happy to be an unconventional female. As to what that means it all gets difficult and so highly subjective that I really think this is one of those honey trap questions that therapists ask when they want to create something to talk about to fill time. It all looks deceptively simple until you actually try to answer and then you find that every single person has a slightly differing take on it.
I mean all the obvious ones like masculine is physically strong and robust, Masculine is practical and straightforward, feminine is emotionally complex, feminine is soft and nurturing, masculine is thrusting, feminine is receptive... etc etc etc - except that when you examine any of these perceptions you find that there are always circumstances or individuals for which these ideas simply do not hold true. So as conceptual models these ideas are in fact pretty useless.
As far as my own self understanding is concerned to use a decorating analogy, I'm kind of like one of those near white paints that they sell under various names like "apple white" and "peach white" etc. I'm "tomboy female" and with a good twist of geek gloss-work thrown in!

To be controversial for a moment, I personally think gender is one of those useless concepts invented by people who have limited mental flexibility and therefore have to retreat into the simplicity of rigid categorisation of things to allow them to make sense of the world. I feel sorry for such people, but I have no desire to enter their world in which a rainbow, instead of being a continual spectrum is merely comprised of eight arbitrary fixed colour bands.
My world is in at least 48 bit colour while theirs is apparently only 8 bit! It should be fairly obvious which of us has the richer visual experience! Now perhaps tell your therapist apply that principle to gender and the making of such over simplified binary lists!
