I knew I liked Guys since I was ... what? ... Conscious???
But, being a "Good" Preacher's Son, I did what was expected of me and ran around with all the girls. Besides, it was also the "naughty" thing to do!
Anything involving Human bodies was absolutely "Sinful", so, of course, THAT's what got my attention! However, I never had Real Sex until I was away from Home, at college!

(And, it so happened that a Guy was my first successful "conquest"!

)
But, I kept UP with, and thoroughly enjoyed more than my "fair" share of girls! (Nearly married five, or six, of them! ) And that continued into my late 20's!

(With a few Guys thrown in, here and there.

Though my story isn't like yours, my point is, no matter what our "normal orientation" might be, most of us don't fully realize it until we reach a stage where we're willing to fully accept it. Like a previous poster said, our true sexuality is something that we discover. (It just happened to take me a lot of Experimenting!

)
If I were You, I wouldn't worry about it, too much. Be true to Your Heart, and, as "they" say, "Go with the Flow"!!
And, yeah! ... no matter what ...
Keep smilin'!!
