I cant recommand any girls but i sure can give you advice on how to make your first time as easy and confortable as possible!
Golden rule 1: dont over think it
Most of the time you create an ideal in your mind that will most likely never happen
No expectations: no desapointment
Golden rule 2: quality vs quantity
Whats best? A horrible hour at 200 or an electric 10 min at 500?
When it comes for something that important: do not count!
You might lose the all amount trying to save a few bucks and go home with blue balls on the top of that!
I would not book anything less than at least 2 hrs, not only so she can break the ice but also so you dont stress out over time/ cuming multiple time...
2hrs is pleinty of time to get most of the kissing- caressing- 69ing-doggie styling.... Etc!
Good luck to you!
Dont forget, dont be cheap when it comes to important things!
Quality vs quantity anyday
