LDR first meeting...

Okay guys, I need some advise! I met a guy about a year and a half ago on a random app. Sounds sketchy, I know. But we became friends and then... more. Texting everyday and FaceTime constantly! We live VERY Far from each other but I have never had such a strong connection with anyone else in my life. So we decided we finally are going to meet. We are taking a vacation together in December and I can't wait! But here's the deal, I'm a virgin. So I would love some advise on what to expect in the "Sex" aspect or if any of you have met in person someone you met online...
