The conversations for me have all pretty much gone the same way. Initial confusion over the difference between gender and sexual orientation, then an overly simplistic "so you're a girl in a boy's body?", followed by some form of the surgery question, even if carefully hidden. Such as "How far do you plan to go with it?". After all that gets explained then they don't really know what to do with all that new information and their completely changed view of me as a person.
And I think there's also some element of disbelief. Like they just can't see me as a female or that I could feel like one or whatever. It's too far of a departure from the fake persona I had created to keep the real me safe for them to wrap their heads around, even months after I've told them. A lot of that is my fault though. Hopefully that will change as my transition progresses, we'll see.
