What is my sexuality?

Help:I am wondering if I am bisexual. So basically I'll start telling the "story".Ever since a few days ago, I was wondering if I am bi. This is why I am wondering...I always have liked females since age 3-present and I always will. I always (currently) picture myself with one and want to marry one and have kids one day. That being said, I notice males too. Ever since I think the first time was fourth grade, I saw a boy in the class next to me and I guess I felt attracted to him. I didn't really know what that feeling was...But that was like a one time thing.After that, in fifth grade, I started finding a guy from a television show attractive. Idk why I did, but I did.Sixth grade rolled around, and it never really happened again. People would call me gay, but I knew I wasn't and I know I am not to this day, nor will I ever be. I guess it started back in April where I started to find boys in my class "cute" or in the older grades. It pretty much stuck with me there.Seventh grade, I started noticing guys' bodies and liking looking at them. I would "accidentally" bump into them just to feel what their bodies felt like. (I still like(d) girls.) I love the feel of their muscles and bodies and I have no idea why!Now here I am questioning everything...I hope to marry a girl one day, but idk what the future will hold. I like the looks and bodies of males, but I know or feel deep down I am straight. Idk how I feel that, but I just know it will all work out. Btw, I feel like I would not date a guy, kiss a guy, marry a guy, nor "do it" with a guy. I do find them attractive, but again I don't really feel like I would want to be with a guy, just admiring them and fantasizing about them afar and in secret. Am I straight? Am I just gay in denial? Or am I bisexual?Thank you everyone for reading about my problems.
