My personality changed pretty drastically from male, for multiple reasons. My old personality was characterized by impatience, irritability, anxiety, and a temper that flared at the slightest frustration, and all that vanished when I started hormones.
There are also multiple dimensions to me now that were only hinted at when I was living as male. It amazes me how much patience I have now, and it amazes me even more that I can sit back and coolly analyze situations that would have had me fuming with rage in the past.
My taste in clothing now runs to pastel tones that as a male I only wore back in the Miami Vice eighties.
My taste in cars is somewhat more feminine than it was before, and now runs to Mercedes cabriolets and Saab convertibles, where before I liked Lamborghinis and Mercedes AMG coupes.
And I've gone from being a beer drinker to more of a wine connoisseur.
I already liked gardening, home decorating, and architecture, but I like those things even more now.
I was always a little bit geeky myself, and I still am. YMMV.
