What gender preference do I have?

all my life, I've been attracted to guys, so I'm pretty sure I'm hetrosexual. Am I still straight if I don't mind the thought of dating a girl? But I've never had a crush on a girl before. For me it's just the person I like matters, not genders and for tht reason if my future s/o happens to be a girl then I'll be a lesbian and if it's a guy I'll be straight. I don't understand much about different sexualities so forgive me for being ignorant.
