Mistress Rogue is well regarded, but I've never actually sessioned with her. I've been doing the S&M thing for donkeys years and nobody in Brum appeals to me. If you're willing to travel I'd try Mistress in Latex in Lincolnshire as a first timer. Mistress Maxime would be closer to you, but I'm pretty sure she doesn't even give hand relief! Very skilled though.
My attempts at getting escorts to do it has been a bit of a disaster, so I'd suggest seeing a pro instead.
