Confused

so this post is probably gonna be like every other one in this category. basically, I think I might be bisexual but I'm not sure. I'm 16 years old, and I've never had a boyfriend (which is chill, I don't feel pressured to have one). I mean, I've had plenty of crushes on guys but I've always been too scared to make things official. I also think about girls though, which really has me confused because it tends to be girls I don't know (like the waitress who served me at a restaurant or a shop clerk) but for some reason I'm attracted to them, and it's a really strong attraction that gives me butterflies and is constantly on my mind. lmao at first I thought it was love at first sight. I don't think I've ever actually had a crush on a girl, per say, but I'm still confused. some advice would be really great 😣
