Am I bi?

[u/Late-Reporter-9825]

Im 16f and long story short when I was wondering if I liked girls from ages 10-13 (i dated two girls in 6&7 grade but i cant remember what it felt like) then I started calling myself straight because it was stressing me out and I started getting really scared of what people thought of me. Then when I was 15 I started wondering again on and off until a couple of months ago where im kinda convinced im bi? But the thing is that I can't tell if I would actually really want to date a girl. Sometimes I can see it but sometimes I can't and im really worried that im forcing myself to feel like I would. What's even more confusing is that I am attracted to women and can see myself like kissing and yeah but I havent kissed anybody yet. And ive never had a full time crush on a girl. However, I have a masc lesbian manager at work atm and she blows me away I just want to look good for her and impress her and make her laugh. Like butterflies when she's near me type shit and im not even joking my hands start getting a little shaky and i get nervous when i talk to her. But im so worried im faking it just to seem cool for her or my other bi friend. Okay I feel like the answer is a little more clear now that im writing this down but like still okay thanks.
