Hello!!!! I'm a fellow Hoosier too
Yes, unfortunately Indiana don't recognize us as our true genders until we had SRS :\ . They are very strict when it comes to gender changes markers on IDs and must be documented that you had SRS. My best bet would be to ask a therapist, and I know a real good one in Indianapolis if you need her contact.
I'll be moving out of Indiana next year into PA, which just requires my therapist to sign off on it which will enable me to have my gender marker changed from M to F.
Take care and hope we get to chat up more!
