ajj,
I was in the same situation and I looked at the adult-london site. I picked Zoe because she was the cheapest of the girsl with ads there. It was hard to get her on the phone, I guess shes really popular and sees alot of guys. Shes not doing outcalls, so I went to her place which is a dirty mess and kinda gross. Her ad says shes 25 but she looks much older, and shes a big girl. When it got down to business she was great - what a screamer. She looked like she had more fun then I did and couldn't get enough, though Im sure she already had a whole bunch of guys that day. Shes nice but kinda weird, maybe I repeat ... but want to try some others first. Let me know if you find someone good.
