i don't know what is my sexuality

since i was little i always adore girl like i don't want to see them cry or sad i just want to make them happy. when i have a first crush on a boy my mom was happy when she know that because she relief that her daughter is straight and when i getting older i always thought maybe i am bi because i like boys but when i near this girl who i think she is beautiful my heart start to pump like really fast...

I don't know if you guys will understand what I was trying to say but I'm so confused because in my country LGBT still banned
