What happens in Vegas

I’m taking a trip to Vegas to meet up with a guy and hangout for a couple days. We both want to have sex lol. It’s our first time meeting tho how do I keep it cool and not awkward? We’ve talked a couple times on face time for hours even...we talked twice for like 8 hours straight. So I mean of course there are awkward moments, but in person things can be different. We seem to get along just fine, so I guess I’m just a tiny bit anxious.
