I need help with what I identify as...

Ok, so I need some help. I’m not sure if I’m bisexual or straight. I’ve been thinking that I’m possibly bi for the past couple of months. I’ve only ever had romantic feelings (and sexual) for males, but sometimes I’m kind of sexually attracted to women as well (I’m a female) so I’m not sure. Like I said, I’ve never thought of dating a girl, or anything romantic, but sometimes I will get turned on by a female and sometimes want to engage in sexual interaction. I’m just really confused, and I don’t know, maybe I need more time to think things through, I’m only in 9th grade, and I’ve only been feeling this way for the past months, so you can see why I might need more time to figure things out. Can you please help? (Also sorry if I rubbed off the wrong way, I can see why people would think that)
