Danm, this thread took a turn...
First off, I joined about a week ago. Cost me about £30 with processing fees.
Secondly, inviting an escort to your home just seems crazy to me. Outcall as far as I'm concerned would be to a hotel you're at and I always pay in cash. In or out.
For a better punting experience I'd find a girl with good feedback on AW that is English. And don't skimp on it. You'll be able to ask for what you want that way. Then book on AW and formalise over the phone. If she thinks you're going to be giving feedback she might perform just that little bit better.
Good luck in the future.
