Straight,bi, bicurious, lesbian?

im around 13 and have always thought girls were pretty and guys were cute. ive always had crushes on guys, but never anything deep (i know im young and that's prob the reason why) and when i crush on a guy, i blush uncontrollably, get butterflies, don't stop smiling, daydream, and imagine life with them. but i can never imagine being in love, or crying over the guy. now i do tend to look at girls "assets" like boobs,hips,butt. but i get no arousal over it, more like i wish i had a body like that. but every since i started questioning my sexuality and girl crushes, i think i chose a random girl to try to experience what a girl crush is like with.. so now i think ive tricked myself into thinking i have a crush on this girl. i dont really talk to her, but i feel the need to be close to her and be her friend. and i try imagining kissing her and other things and i can imagine it but i wouldnt want to do those things. and then i think about guys. it takes a lot for a guy to "turn me on" but it has been done. and i can imagine sex with a guy but right now, i wouldnt want to see any of that. im guessing this comes with maturity but idk. this is weird. i dont know if im straight, bicurious, or bi..even though i very much know that no one can tell me what i am, what do you think?
