In the event they do start functioning normally don't stress out. You are going through puberty and will have your body do some pretty insane things to you. Up to and possibly including going from being attracted to men, to women, then back to men, then(in my case) liking both!
You might start functioning again as well. In this event I wouldn't be concerned unless you start getting the random erections and other such things that you use to get from T. If it functions when excited and in the heat of the moment then that is also very normal even on max dosage of E and with an orchiectomy it still can.
Other then that sounds like you are very well on your way sweetie! Hold on tight and enjoy the ride cause it gets very interesting, often times frightening and always exciting!
As far as the male drive, it's a ymmv thing again but I can say the way my sex drive functions now is very, VERY different then before, so pay attention to when you do get excited and see what it feels like. You may just surprise yourself!
