Hi Bancho
Being a non-religious, non-American, and female; I am of course fully qualified to discuss this

I do a little bit of counselling for MtF mainly, but I also do some 'harm protection' which is different of course.
One thing about 'coming out' is that there is no going back. There is no way I can go to work in a dress and say next day it was a joke.
There is going to be a point in time that I can hide my breasts and pretend they are not developing. There will be no going back. Walk into work; Hi I just thought designer boobs was the in thing for guys this season

There are check points that we live with, and we have to be very certain that we can cross them because there in NO going back, the line is erased.
There is no way you can go to your pastor and tell him that you are male and are going to get the physical transformation to match your gender. Or even not go onto T and hope that people will forget. Once you step over the line the line has gone. I have no idea, obviously, what your community is like. If it is small and homophobic and fundamentalist, welcome to misery. Because no one will try to understand you. It is not in their interest to understand you. In fact it is against their interest.
Traditional religions are based on conformity, without getting into religious arguments, and please don't, most religions grew to allow a society to develop. (Sorry for this) If you couldn't steal his horse, rape his wife or kill him there was a chance that a community would develop.
So where does that leave you and your girlfriend? How accepting is your community. Early days, but say you start living together, can you? If she wants children, and most women do BTW, are you and the community OK with adoption and/or artificial insemination?
How comfortable will you both be, walking down the street holding hands and having a kiss under the mistletoe?
Oh and why lurk?
I think you will find we are a very accepting place.
Merry Xmas Guys
