I have feeling for a guy for the first time what should I do?

Ok so I'm a 14 year boy and only have liked girl or at least not Recently. There's this new Guy that moved on my street. He's my age, he's a little taller than me, black/brownish hair, and the greatest smile in the world. So I got to knew him. And he's a pretty awesome guy. We have a similar taste in almost everything. I just don't know something about him that just makes him really fun to be around.and that's been going almost everyday for nearly a mouth and it's been fine, we've been haging out with each other. But than a few nights ago we were watching a movie. We were having a really good time making fun of it (it was one of those movies on Netflix that just looks stupid.) any way after the movie was over we didn't say anything. It was a weird silence. We started talking about how much fun that was, how it was a good time. Than he kissed me. I was shocked, yet not grossed out as I thought I should have been. He start to say he was sorry but in mid sentence I kissed him. I don't know why I did, I guess it was Just instinct. But it felt oddly good. He said he had to go right after and just left. We have talked back yet. But the thing is I want to try it again something about kissing him just fells right. And if not i just want to still hag out with him. How should I do this? Am I bi?(I've only liked girls before) just what should I do?
