My eyes are exploding right now!!!!

I just met this guy at a local fair, and we had so much in common that we became INSTANT friends! He’s such a good guy, and I actually kinda like him... like a LOT. He just asked me out and I don’t know what to say! HAAALP! I don’t know if I should say yes, because he would kinda be my first boyfriend....

I don’t want to screw it up. Like saying something I shouldn’t say. But I also don’t want to be moving too fast because we met just this week. He’s helped me through quite a bit already though, and worked me through a couple of panic attacks and such. Should I say yes??? Please help me!
