I agree with Charlieton,escorts do state on profiles to e-mail them or phone them,in my experience of using Adultwork the girls prefer to be phoned first,most escorts do not respond back to e-mails.
I would suggest look at escorts who have over 100 feedbacks left by different punters,there are many multiple feedback leavers (guys who keep seeing the same escorts).Pimps are getting very clever these days at writing escorts profiles.Some foreign escorts command of the english language is not very good so pimps write a top notch profile out for them.Not all escorts on Adultwork have pimps,but many do.
If you have a car and it is not to much hassle to drive to london book an escort called Justina on babylon escorts.She is bi-sexual and likes to meet couples i have seen her many times,but not for a MFF session.she's a very sexy busty lady and she is in South Kensington her fee is 150 an hour.
She is a well reviewed escort,she has about 150 to 200 exellent reviews on various escort agencies she is on.
