My unsolicited advice is: whether they realize it or not, _everyone transitions_ ;) http://okayfail.com/garden/everyone-transitions.html
I came out socially for most of a year before I committed to hormones, and it took me another year and a half to commit to removing my facial hair. At some point it really is a leap of faith. But you can do a lot of exploring and trying things out until you feel comfortable – or decide it's not really what you want.
Either way, good luck!
