I've been questioning my sexuality

I've been thinking about my sexuality for a long time now, I'm 16 and I've only ever dated boys but I know I like girls too. I know I would date and love a girl just as i would with a boy, I like both. I'm worried that I might be wrong just because I've only ever dated boys. Is wrong for me to day that I'm bisexual if I've only ever dated boys.....
