Privacy vs. Verification
You need to have anonymous email accounts for the internet. You can use aliases to protect your anonymity, but eventually you will need to allow the escort to verify who you are. If an escort cannot determine that you are not a vice cop or something, you are leaving it up to them to not see you, or take a chance on meeting an undesirable client. Show her some trust and respect, she is taking as much a risk as you are.
This just makes everything more expensive, and less pleasant. If your escort never has to deal with no-shows, undercover police, bad apples of any kind, then she/he will provide you a better service, and will be less expensive for you as well.
In order to enjoy the services of a female escort, you need to learn how to discuss her adult services correctly. In order to discuss anything intelligently, you need knowledge. Escorts do not sell sex! As a matter of fact, you can pretty much insure yourself a really bad experience with any escort if you ask her how much it would cost to have sex with you.
Escorts are like any other woman, if you are nice, clean, respectful, polite, and fun to be with, she will probably like you enough to consider getting closer to you. But you have to do your part first. If you walk into this with any expectations, you'll only disappoint and frustrate yourself.
Leave the donation for her time on the dresser. All escorts will tell you what they expect in pay, before they get there. Don't make the escort ask you for money. You'll only look like an amateur or a schmuck trying to rip her off!
Don't talk about sex! Period!
Have your ID available, if asked, for the escort to examine if she/he chooses. If you don't trust your escort enough to see your ID, then you need to look elsewhere for companionship. Escorts will be so much more comfortable with you and you will have a better experience if you follow this advice.
Lastly, don't be mean or rude to her, don't be high on drugs, don't be drunk, don't try to rip her off or "short" the donation envelope. If you treat her badly in anyway, not only won't she ever see you again, she may put you on a bad client list type web site that warns other escorts about you like NationalBlacklist. Then other escorts won't see you because you've been blacklisted.
So, just think of her like any other date and have fun and be cool.
Enjoy your date.
