Your wasting your time with nonprofessional providers!

I prefer to book way in advance & always get the juicy details needed to book out if the way, so we can play with no problems.  Sometimes I book 3 months ahead, or even 1 month it just makes the time together better when we have been anticipating the playdate well in advance.

I always need to book well in advance because I have a busy schedule with too few windows of possible playtime, so if I contact a gal who seems unwilling or unable to carve an appointment into her calendar a few weeks in advance I just say 'next' and contact another gal. There are plenty of gals out there who run their schedule professionally.

I have had people book a meeting up to a year in advance!
Nothing wrong with knowing what you want and planning it all

Also, on a side note. I always see OEM throughout the boards. What does that stand for?

If they don't show you the common courtesy of responding back, esp in this day & age when we all practically have email access on our mobiles. (so no excuse really, for one not responding). But if they don't reply back, then it says a lot!
And if they reply back with *that works for me* but doesn't screen you. Run! Because if they don't care enough about their own safety. Then they sure as heck don't care about yours.  

There ARE ladies in this adult hobby who screen and who will allow you to book in advance.  
 

My advice to you

Whenever there are advanced bookings from out of towners, I always re-confirm the day before and the day of. I remind them that I will confirm right before, even during non-advanced bookings.  

With that being said, if you are adamant about seeing one provider, it may help to take the reminders and confirmations upon yourself. Of course, a well-reviewed and verified provider is less likely to forget.  

At some point during your role as a hobbyist, you should try to get into P411 and date-check. Some of us ladies (including myself) are active members of those sites for verified providers and hobbyists. Ladies reaching this level of verification are responsible and savvy and will not flake without letting you know in advance.

If you are new to them they probably aren't taking you seriously.  they get tons of emails like yours so untill you prove yourself as serious you are just a shopper. And quite frankly it sounds like your still in the shopping mode.  

Suggest you settle on one, show her your serious, and plan around it.  Check out reviews and make sure she is legit and dependable and use her desired contacting criteria.  That said, have a plan B if it falls through
