Im really confused, & to the point where i might be what my family is against! Dx

Im a fourteen year old boy. && i don't know if im straight, bi, or gay? l;
I like girls, I have crushes, & feelings for them.
Like this one girl at my school who
ive had my eye on. Ive actually had my eye on a couple.
I have actual feelings for girls.

But with guys, i just think some of them are really hot, & cute.
Like i would just give them a beejayy & maybe have sex with them.
But i would have sex with girls too, even if i am a virgin. BOTH WAYS!
My family is against gay people and is yes on prop 8.
No one knows about this. So please just help! Im really confused.
& "NO NEGATIVE SHIETT PLEASE".! >.<
Did i say fourteen. Sorry i mean fifteen. I just turned it like 3 weeks ago, & im not used to saying it yet. (:
