future BF!......maybe?

I'm having a hard time knowing if I should go out with this guy that I've been flirting with? He is amazing and super hot (well to me of course) but he seems like someone who would make me happy. He wants to take me to the pumpkin patch on Halloween. I'm 16 and he's 18, plus I don't even know how to tell my parents about him!?!? Honestly I am freaking out because this would be my first relationship! AAAHH WHAT SHOULD I DO?
