I like to plan.  I often have very specific requests that require some advance work.    As an example,  if I want a sex swing, it needs to be set up and available.   Things may require some shipping from Amazon...  Sometimes terms and conditions need to be agreed to because the standard menu may not cover it.   A provider might not be interested in a particular idea for a session and I may need to find another.  

 I often give my session a lot of thought. To me P4P is fantasy more than it is sexual release.  I do one session a month on average.  It's not an every week or every other day for me.  Further,  If I have a clear expectation of what I want, she has a much better chance of giving it to me.  

There are practical reasons as well.  I only know a limited number of providers well enough to do last minute.  I also book multiple hours.  So unless the provider happens to have a large hole ....in her schedule, it ain't gonna work.  And I hate disappointment...

The reason for my OP is that since I do plan, I need to put "schedule the provider" into my timeline.  Further, there have been some posts regarding the issues with planning too soon.  I used to try and schedule a month out.  I have run into some issues with that.  Two weeks seems like it works for me.

 On the other hand, one of these days I might give one of the ladies I have seen a call to see if she has an immediate opening... in her schedule and otherwise..
