Best advise I can give for a first booking with an escort, 30 mins max. Main reason if you don't click or get along then an hour is a waste of money and it get's awkward.
The Adultwork verified and feedback system is not great, but I usually look at some feedback and the private gallery to check things over and see if it looks legit.
This forum has reviews so search to see if any bad reviews etc
Avoid Romanian's. Nothing against them, I do see one nice one. But usually they take the piss. More than other nationalities and you will leave disappointed.
Also, decide what you want from the booking. Very important. It's a service and business translation between you both. I can't really talk or give advice about not getting attached to an escort or emotionally involved. But try not to. In most cases you will simply be giving more and more money to the same women in pursuit of something that will likely never happen.
So set a limit on the number of times you see the same women. And have a few women on the go at the same time. If one or two are really good and you get along, then she maybe a good regular.
Feelings can develop, but usually in most cases it's one sided and she will simply be happy for your money and the time you spend with her, and that your happy with the services she provides to you.
In rare cases, you both might get attached to each other. Really that is a mind field! You will know as you no longer pay and it's basically a relationship from thereon. But sex work is her job so don't expect her to give it up for you. Though she will expect you to give up punting (as it's just a job to her but pleasure for you).
Also, sort out what's on offer and the services either before the visit and BEFORE you hand over the money. Also don't fall for the £20 extras for services once the appointment starts.
Get it all agree upfront and you and her will have a good time. If you don;t like what you see, walk away before you give money.
I have seen 100's of women but still got caught out recently, she was super good looking, really friendly even tried to get me to do an hour instead. But stuck to 30 mins. And once the money was give, one of the most objectionable women I have ever seen! She even had good feedback on AW and a waiting list of clients.
So not to put you off, go and try it and you might like it. But for me, too many women, too long and recently too much drama. So I feel like I want to quit.. But it's very difficult to stop. I have spoken to a few regulars and it's the same for some women. They stop for a little while, but the money is too good and easy so they return.
Also stick to a budget. I spend £1000 a month. Others on here might maybe spend a few £100 a year.
But have fun and good luck!! Mid-life crisis time for me now
