Totally agree w/ Tori!
I think you're going to find that E is just another pie slice out of the whole transition process. It does help, but it probably won't be the end-all solution.
Also, gender isn't confined to the binary roles of male and female. Gender is extremely fluid, and you should never even have to worry about if you feel like a male or female. Ultimately, with the lifepath that we have been given as transsexuals, there is usually a bit of both in there and it can be overly apparent to us- even possibly a cause for some transition anxiety.
Cisgender folks feel the same thing (gender fluidity is not limited to trans people), but many do not know how to express it and fear going against what society and culture expects.
I think the big takeaway here is that you should just learn to accept yourself regardless of gender. If something makes you happy, then do it. Try not to get hung up on the question if you are male or female "enough". You are you, you are unique, and nobody can tell you otherwise (not even society at large). Being trans gives us a shining opportunity to truly express this fact, perhaps much more freely than the average cis person. ->-bleeped-<- does have its perks
