Am I bi or ?

I knew ever since I could remember that I liked girls.Feelings starting progressing as I got older, and I liked guys also.When I was 14-15, I liked guys and girls equally.But now I'm starting to just like girls more.I don't even care about guy anymore.Its like.."yeah, there good looking." If I see a nice looking guy walk down the street It just doesn't matter to me no more.But Ill be riding in the car with my sister or someone and Ill look at a whole bunch of girls.I have a friend whos gay and I talked to him about it, and hes asked "Well think about male celebrities that you would want." I used to love Leonardo DiCaprio when I was younger, I still do, but just as an actor. I think hes cute, but not like that. And I don't want to get married, I don't want to have children.Thats not in my book of things to do.I just don't know, right now I know that I like girls...alot ;p and I really don't care what people think.My friends+family are accepting.
