I'm sure I'd be exactly the same.
Personality and who you are is something that builds up from social contact, experiences, etc.
Ever since I can remember I was not allowed to leave the house to go outside whenever I was home. So for me it's always either be in the school building or in my room. I moved a whole lot so my only friends have been over the internet, and those have been the people that have influenced me to be who I am today, since my family members rarely talked to me and left me to myself mostly.
So from that I can conclude that I'd be exactly, or very damn close to being exactly the same as I am now.
I'd be an emaciated pale girl with long unbrushed brown hair. I'd spend all day laying in bed sleeping, or in bed schliking (I think that's how it spelled) to shota, reverse-traps, and cunt boys (mirrored all my fetishes). I'd wear some kind of hat when going outside to flatten out the hair and look like less of a mess when going out to lectures. I'd wear whatever I could find in the morning, so that could be anything from really baggy pants held up by a belt or tight fitting jeans. I don't know much about shirts, I guess I'd just wear regular shirts? Don't think I'd be the kind to wear dresses. On the upside I'm a very clean person and always smell nice, so I'm sure that'd transfer great over to female form.
