If your confusion is related to what sort of "title" you should carry in terms of orientation, screw it. You like who you like and nothing on earth is going to change it.
In regards to the christianity aspect, I think making choices to act on or not act on your feelings depends largely on how you view God.
As a personal belief, I know that I trust in Him as a forgiving and loving God- I want to believe that He cares more about your devotion and goodness in life as opposed to the gender of the person you give that part of yourself to.
Some people think otherwise- that homosexuality is a sin and that you'll only be 'forgiven' for the sins you repent. Those people, ultimately, can make the choice of leading nonsexual lives, or they can make the choice to 'force' themselves to marry for the sake of doing the right thing, the one that's 'acceptable' if you're a christian. I've never met any of those people who turned out happy- because no matter how many times you try and spin it and tell yourself that you're "different" or "fixed" you will continue to be who you've always been- and if there's one thing I know, it's NEVER okay to hate even a tiny part of yourself, and this is no small part.
Ultimately, you get to decide which of those choices you want to make.
