Well, I figured it was about time to create an account and introduce myself since I've been reading the forums for a while.
I'm Katie, and I'm a 33 year old MTF about to start hormones next week.  I'm planning on coming out to my wife this evening and even thinking about it terrifies me.  I know a lot of you have been where I am, so it's great to hear all of your stories.  Hopefully I will be able to help others with my experience in the near future.
