I'm currently in university and not being paid anything, so the question for me is really just "would I be happier if my sex was different".
The answer to that is... complicated? I'm tempted to say "HAH, sucks to be you OP, I'd be unhappy either way", but recently I've gotten how I feel about myself in a good position? So I wouldn't want to throw that out the window on a chance.
If the time period was smaller, say a month, I'd consider it, but a year is too long. Alternatively if I could pick and choose characteristics that would be more appealing, but if I wake up and suddenly I have massive boobs then that's gonna be a thing I'll be dysphoric about.
