She was 100% bullshitting you. Its harder than you can imagine to get somone to join you and even harder to get someone good.
Advice
No.1 top advice.. the FIRST TIME you do it, concentrate on your wife, kiss and caress her, and (as much as you can) ignore the escort.
Get somone for your wife not for you (looks,figure wise).
Do candles/music/wine all the bollocks you have (probably) stopped doing with your wife when you are horny and just want a shag.
If you have AW feedback already yourself, then you need to speak to the girl and expalin things like outfit/hairstyle/underwear that YOUR WIFE likes.
Break the bank cost wise.
The first one should be perfect for her and a headache for you, to ensure plenty more
If you're interested in some names of escorts I might be able to help depending on the area.
Definitely name and shame, she was bullshitting you, backed out, and had no intention of ever seeing you and your wife. You wil be saving other couples the same bollocks you had, and giving back to the site.
