Going on my first date ever with another guy and would really love some advise?

So I'm going on my first date tonight and I'm kind of freaking out. I've been talking to this guy for a couple months and we have hung out once but this is the first official date and also my first date with another guy. I don't know how to act, what to do, where to go, what to talk about etc. He's much more experienced than me having a couple boyfriends before but this is so new to me that I don't even know what to think. How do I just relax? Does anyone have any advise about first dates? I'm just full of nerves right now and can't think of anything besides tonight. I'm almost shaking typing this out because I can't even believe this is actually happening.Edit: I should also add this is the first person I've ever been this serious with when it comes to relationships, which is just making me more nervous.
