<human>: I like this guy A LOT. I've never been the relationship type of girl, because I've always enjoyed dating. I'm 23, fit, pretty, and I go out on dates 2-3 times a week, usually with all different people. I like flirting and getting asked out... just everything about dating.

But I recently met this guy that I cannot stop thinking about. Our first date lasted almost 9 hours. We just talked and laughed the entire time. I'm falling for him really hard. 

I'm absolutely terrified of screwing this up. My new boyfriend and I have already discussed exclusivity, and we would both like to be only with each other. 

I think I'm just really scared of being in a relationship. I've never done it before. It's incredibly thrilling and exciting - I've honestly never felt this way in my life. But I'm also so scared of myself in this situation. I don't want to fuck this up.

Oh I should probably mention that my boyfriend lives a 3.5-4 hour flight away, so we're long distance. He flies in weekly to see me and we FaceTime 1-2 times a day.

Can you condense the text into a few key points?
<bot>: I'm entering a real relationship for the first time in my life, and I'm terrified of doing something that will jeopardize it. Any advice?
