Am I a lesbian even though...?

Im 13 I think lots and lots of actresses are hot(I.e Megan fox, carrie underwood etc) and i have crushes on 6 girls at the moment(2 are wayyy older than me) but the problem is i can't see myself having sex with any of them or marrying them or having a future with them. I'm able to see me dating them I guess but I don't see myself going any farther(that might be because I can't stay in a relationship to save my life) I also am in love with guys. Like I Am legit in love with most guys and I can imagine myself with a guy! So I just wanna know.. Am I bi or lesbian even though I like girls but I don't see myself being intimate with a girl and will probaly marry a guy?
