I don't see my gender-related feelings as being dysphoria exactly, they seem to be more just feelings of alienation from what people assume I am / expect me to be.
I still present as male, and last night I had an experience of feeling rather alienated.  Our chorus is planning to have just the men in the chorus sing a song about "watching girls."  It's a nice enough song musically, but something about being among a bunch of "guys" singing about ogling "girls" just felt 
so "not me."  It's not that I don't enjoy looking at women, it's the girl-watching/girl-ogling/girl-objectifying pose/culture that bugs me.  I felt like an atheist at a tent revival.  It just kind of slapped me in the face with the fact that I 
don't feel like a "guy" and don't want to.
And the women are working on the song "I'm so pretty."  I've always had this secret desire to look and feel pretty (fat chance 

 ), plus I love the song anyway, and I so wish I could be singing 
that song instead of the girl-watching song.  The sad part is that even if I transition, I probably still won't be allowed to sing with the women, since I'd probably still be a tenor and not an alto.  There's a woman tenor in our group, and they aren't having her sing "I feel pretty," either.  (They'd let her sing the girl-watching song, but she isn't willing to.  I don't blame her....)
I guess this is my subconscious telling me it's time for me to get off my butt and start transitioning, right?
