Yeah... Nebraska. You might want to move.
A lot of states require top surgery for gender marker change... in California it is required to change it legally, but your state ID gender marker can be changed with a simple doctor's letter... otherwise, mine wouldn't say M when I haven't had any surgery. Probably the best state, as far as gender marker goes, is New Mexico. They require nothing but that you fill out a form.
If you want right to marry, as well as people who are as welcoming as possible of who you are, you might want to consider relocating (eventually) to either the east or west coast.
