it is good idea, however i am taking 2hrs even never met, yes...sometimes really too long and they are too much stamina..or something else! yesterday one that really was porn style. I am accepting anyway for financial goal and i try to take more longer as much as can!
once i am in the booking time go fast! 1hr + 1hr from different punters means you work more! time to get ready, email, text and all staff! finally you work more with short booking (my opinion)
i prefer long, suffer maybe (not really, just more tolerance) and more discreet as well!
then depend about preferences! you can always propose shorter, when i did they always accepted that! many times i regretted to propose it
