Lesbian or bi??

Hi ummmmm so I'm 14 years and I'm not sure about how I feel for girls or guys. I mean like I grew up liking guys but lately it's like that's disappeared. I have this feeling for girls for a while now but I've also had feelings for guys. But like I said that's kinda gone. I'm not sure anymore. I've always wanted to try having sex with girls idk if I can even call it sec it just seems so normal than guys. Help
