would you consider me "gay" if...

the other day, I went to this really good itallian restaurant, and I saw this extremely hot guy. I really liked him. He was sitting at a table next to the one I was sitting at, and we were kinda facing eachother. I kept looking at him, and like I would smile at him and stuff, you know, my sorry attempt at flirting.

Well, anyways, he got up to go to the bathroom, and I realize, it's really a GIRL!
I was like wow!
I was flirting with a girl!
Not that there's anything wrong with it. I'm straight tho.
It was a girl, dressed like a guy, and she looked like a guy.

So, my question is, would I be considered "Gay" or "bi" if I still thought "he" was hot?
Lol I'm confused. Like the fact that it was really a girl didn't change anthing. I was still attracted. But like, I've never been attracted to girls.

I'm confused:(
