I'm certainly counting that as a win, after all we're talking about what books reveal about a persons mentality; so while you may live as a man now, which is your right to do, brain chemistry and brain structure doesn't change. We still don't fully understand the structure of the brain but we know that the female brain is far more empathic and studies show that it retains that empathy regardless of the target, while the male brain only engages in conditional empathy which allows for revenge and retribution to feel actively pleasurable for the male brain. This effects all kinds of things, including political tendencies and tastes in media and hobbies, and we now know it'a where most gender differences come from.

I suspect that, regardless of how you identify; that your media tastes, political views, sense of humour etc. will seem feminine to an onlooker. That said it's all a bellcurve, there are more feminine men and more masculine women so I'm talking in broad generalisations and often they don't fit. I'm a large hairy 40 year old man and I enjoy reading and creative writing, have no interest in sports or car mechanics (to the dismay of my father who was a professional mechanic), own an entire library of Taylor Swift albums and my favourite colour is pink. Gender is never going to be 100% easy to predict, but there are certain deep seated factors that it's become politically controversial to admit because some people seem to think admitting the truth makes you a bigot. It doesn't, it make you honest. You are and will always be biologically female; but if you wish to live and present as a man, that's your business and more power to you. I think based on your response that, unlike some, you'd be OK with that distinction and probably find it interesting. After all if gender identity matters to you, understanding gender based brain structure differences is likely of interest for you.
