In Dallas I prefer outcall, at least for the first meet. As friendly as I am it is always a little awkward waving to the pimp on my way in (not all of them have one but it in Dallas it is common). However if you are married you may want to use her incall so nothing shows up on your CC, unless of course you are on a business trip as you said.
If a lady doesn't mention screening requirements you can always PM and politely ask. You may also want to PM a recent reviewer. Don't text unless her profile or site says that is her preferred contact. Every lady is different, but they get quite annoyed when you don't follow the instructions in their showcase or website.
Any lady that gets annoyed by your request to use a cover is not one you want to see. I don't think any of the reputable ladies would mind at all but I leave that to them to answer.
My policy is to never give out RWI (personal info). Here's why: https://www.eccie.net/showthread.php?t=2018545
It has prevented me from seeing a few ladies but I always let the big head prevail. Between all the sites I have enough of a reputation as being a thoughtful and reliable client. So find some newbie friendly ladies and build from there. Otherwise use P411 and only P411 if you need to get verified with personal info. Absolutely do not ever use your real phone. Get a second burner phone or an app like Burner or Sideline. Each option has its pros and cons but I prefer the burner phone. If anyone asks about it I say that I found it in the street and was waiting for the owner to call. Never bring them to your house, favorite bar or restaurant, or anything else that traces back to you.
I say all this despite the fact that most of the ladies are wonderful and trustworthy people but it only takes one crazy lady to upset your life by calling your wife, your boss, wreck your rental car, or worse. If you hobby enough you'll run into one eventually so be discreet.
Be courteous and polite, think with your big head, and you'll be fine. Good luck!
