Well, I finally broke down and told my parents, with a ton of prodding from my wife as I was in the process of chickening out and she knew it. Mom took it in stride, and didn't show her feelings on it either way, dad focused on my relationship with my wife, but is not entirely accepting of the changes to come. He said he will eventually come around, but it is a tough thing to deal with. At least they're processing it, and still love me.
My wife told one of her friends, who basically said if you love him, stay with him. My wife loves me and uses both male and female pronouns for me. I'm not going to fight her on it right now, but I really prefer the female ones.
My wife also told our niece. Our niece is my age as my wife was the youngest in her family, and I the oldest in mine. Anyway, she said that my niece said that I was having a midlife crisis. I am afraid that she may be right, but I feel so much better now than I ever have before, I feel like that's not it.
