I personally think that if it is a
legitimate request and the person that is inquiring via pm or email has
taken the time to know what a ladies rates, screening and other information is and required, then the response shouldn't be less than an 8 hour window. That would be the professional thing to do. Now if a guy is just sending a pm or email saying some silly things with out giving pertinent or relevant information that has nothing to do with requesting/screening for an appointment then in all likelihood a lady will not respond.
Example of one email I got just the other day:
"Wow, you are a beautiful woman! I would love to lick you all over and give you a massage! What do you say? How about it?"
----------------------------
You see in that email above there is no real information or anything relevant to respond to.
Here is an appropriate email that a lady will respond to:
(Fictitious this is just an example):
Hey Sensia,
My name is J*ck and I found you on eccie. Here is my handle Up**town** you can see my posts and reviews on eccie. I am a 48 yr old white male, grey hair, blue eyes, 5'8", 210lbs My phone is 281-9**-**** and my references are Candy
see her showcase here and Julip
see her showcase link here
Both ladies saw me last month and can vouch for me. I am looking to get pre-screened so I can set up an appointment with you for next Thursday and 1pm for a one hour massage. Please get back to me once you are able to verify my references!
--------------------------
You see if a guy takes the time to see what the lady is requiring for an appointment and he sends an email like that your chances of getting a response are far better.
Yes we get inundated with pms and emails, and some get too many texts (some downright annoying).
Now to the OP if you are sending emails or pms like the one I made up above (the preferred method) then it shouldn't take a lady any longer than 8 hours or less to respond to you. Some of us are busy with appointments and are not able to sit at the computer 24/7 So it takes time to get back to a request.
