I think I might be bisexual (I'm a girl). Dunno how to be sure, or even what to do about it?

Hey guys, need your advice. I have been born and raised (still living) in homophobic county. To be completely honest I didn't even KNOW about LGBTQ till 3 years ago or so. I found out that people can be attracted to the same gender 3 years ago (I was 17 at that time) when my English became good enough to read novels and communicate at least B2 level at that time. My first MM read was "Red white & royal blue", and after that I became curious and reading more MM and FF books to figure out more about it. And then I met a new girl in my class, and thought we could be best friends since I always kind of been drawn to her since the moment I met her even though I really didn't know why. After discovering that it was possible to be attracted to the same gender I finally realized that I might be drawn to her because I was attracted to her. However, before I could figure it out that friend of mine has already moved to another country. Over the last 3 years the similar attraction happened with several girls. I am extremely confused But I can not talk about it with anyone I know since I live in homophobic country and they think that it is unnatural like the same gender in THAT way. Frankly speaking, I have not been homophobic from the moment I found out about LGBTQ, it never seemed weird to me to be attracted to the same gender (the though might even turn me on a little). I have never ever had any se*ual experience with ANYONE, Neither guys nor girls, but I do know that I am attracted to guys, though I am not sure about girls. What do you think? What should I do now? Am I bicurios or bisexual? What should I do about it? Any thoughts, comments or suggestions??? Pls??
