A premium bullshit attention seeking post. 
He has had all this time to tell us who the girl is but has not done so.
Think about it.
Your wife/girlfriend picks up your phone and hears a voicemail from a woman, she then gives you a death stare and goes out. Instead of being calm and collected and thinking of a plausible explanation that a woman would accept, namely that you are planning a surprise for your wife/girlfriend and the phone call is from a girl in the shop/restaurant/hotel confirming it, your first instinct is to jump down in front of your computer to tell a bunch of guys, whom you don't know, about what has just happened?
Does that sound like something a logical and rational man would do?
Particularly more so since he has never written a review before, to save himself from being "outed" so he says, a ridiculous excuse since if a prostitute sees up to 50 - 100 men a month, she is unlikely to remember one man in particular.
Do you get to the conclusion that he's just an attention seeking wanker?
