I'm sure we'd all love you to TOFTT, or even Take the 4 - 5 for the team. 
I took your advice and had a dabble, but with mixed success.
First of all when you join you are given a certain amount of free 'coins', or credits. These credits are used in your conversations, each conversation (or post as here in UKP) costs 40 credits. Once your freebies have gone, you can buy more - £17 for 300, but that only gives you around 7 conversations/posts, or £14 for unlimited but this one is only valid for24 hours.
Anyway, putting my location as Liverpool, in browsing there were hundreds coming up in Liverpool, mostly from age 35-65.
I'd say around 40% were offering BB
Most sounded genuine
I picked one I thought looked and sounded good on her very brief introduction. My freebie coins and bought ones didn't last long, towards the end I did ask for her email but she said she preferred using the website so that conversation ended there and then as I only has enough for 2 more conversations, is I spent them on telling another what fantastic legs she had before deleting my profile
In all, it may work, but can work out expensive just talking !!
