Okay, I may be over thinking this whole thing, but here it goes.

This girl I had F-closed a couple weeks ago while working abroad is flying 1200 miles to visit me. She sent me a text message saying, "I'm not coming for the sex, I've actually never seen Arizona before". Then she texts me and says "by the way before I come, you don't have any STD's I should know about do you?". When she flies in, I'm going straight from the airport to a hotel room for a night, then we are going camping for 3 days, then back to the hotel room for the last night. My question is, when should I re-start kino escalation? Or is this necessary. Should I bang her the first night in the hotel room or give it a day or two?

You're definitely overthinking, man.

Start kino escalating right away. MAybe take her out for a drink or two before you go back to the room. If you've already been there, it shouldn't be hard to get back. I'm sure she said "I'm not flying there for the sex" so you don't think shes a slut/desperate/etc.

GL man.

From a girl's perspective here, I have to say I would find it bizarre, if not completely crazy, for a guy to spend a night in a hotel with me after I had flown 1200 miles to visit him and not try to bang me... it'd be enough to give me an insecurity complex for life... especially if I'd already pretty much given him the green light by asking if he had any STD's I should know about!!

Agree with Risktaker0, maybe take her out for a drink and seduce her, try not to come across like you think the sex is a given, that's all.
