I now think I can confirm carpet fitter's information. I contacted the agency and asked about Adelle's services but she said that she couldn't discuss them with me but she then gave me the names of three ladies that she thought I would prefer from Amour. So I took that as meaning Adelle wouldnt have satisfied my needs.
In the end I decided to go with a very well reviewed girl called Jada from Premium escorts and she was superb!
