She posted an ad again a few days later on the ad board, that means she is okay and had received your emails but chose to ignore you. Listen, I've seen and spoken to a lot of providers and one thing they tell me is that some guys get way too personal and ask some inappropriate questions or request in the emails. Some guys send way too many emails to providers before the appointment. That is a turn off for some providers.
Listen, your not getting to know her, your just paying to fuck her. I do all of my talking while we're in person. Some guys just don't understand that. She's not your email exchange buddy. Don't forget to always treat email exchanges professionally. The maybe send about two or three email exchanges max to a provider prior to an appointment. The initial screening email, the response to her email, and the confirmation email (can be a day or the day of the appointment). I don't go sending like ten emails asking how her day was and can't wait to see her, flirt with her, send her my damn photo (why do guys feel it is necessary to send a provider their photo: that's what the ladies tell me), and all of this personal questions.
Just because she has confirmed you as having several whitelistings, provider reference, and know you as safe, that doesn't give you the right to ask all of these damn questions and treating her like she's your personal email exchange buddy. That shit is annoying to some girls. You know how many emails a provider gets when she is touring? You probably turned her off with all of your damn emails and questions.
If she is offering a fetish, be passive about it and don't go into details. For example, I am looking for my greek excursion with you. Pay her the fee extra fee when you get there. Or if you need to make a dress request, say, I like girls with high heels and a mini skirt and hopefully you can accommodate me. That's all you need to say, don't go asking too many damn questions because that shit can be annoying.
You probably left something out in your post, but she chose to ignore you for some other reasons. But from what I gather, you probably turned her off with all of the damn questions and request you had over email and she felt uncomfortable seeing you and so she ignored you.
I don't do a lot of communication on email. Like I said earlier, first email is for screening, second email is for responding, and third email is confirmation the day or a day prior to the appointment. Some of you guys get too damn personal on your email and that can turn a provider off. I keep it strictly professional at all times and do the majority of talking when I'm actually there with her.
