I'm not living full time (barely part time if I'm honest! - waiting for the changes, just like you) so I present as a typical heterosexual dude. Which is a big part of me. I'll check out girls all day long, openly, not exactly respectfully, etc. When it comes to guys, that's expressed more in fantasy, in my mind, in my home! - just has never found an outlet socially in Real Life - and it's felt most often from my femme side. It's mostly a sexual thing tho I have been attracted to a few guys for the people they are. SO *** this little thing I caught myself doing, as trivial as it may be, shows me how I'm changing as my fem urges and instincts take root. The more power and freedom I give them ('her', really just ME) to explore and interact in the world - to just BE, the more I'm noticing. A different smile, a unique sense of style, a new perspective on my art... and certainly new ways of expressing my sexuality.
As much as I'm like "yay, titties!" these little changes excite me as much or more.
