I also prefer the slow sensual disrobing, with me removing her clothing and she removing mine.  Much more fun than just drop 'em and go.

A good provider is there for your enjoyment, and will respond to any reasonable request to increase your enjoyment.

Providers are not mind readers, since what you like is not a sexual act, but a description of the type of date  you want, once you've been screened, tell the escort, you like to "take it slow"  and you like a "sensual" date. Great providers will know what you're talking about.

And what's with the LE check and the ladies you're seeing. If in fact you've been screened, this shouldn't happen. BTW, LE checks are useless, if you're seeing highly reviewed TER providers you shouldn't even have to endure an LE check.

Finally read the "juicy" details, you should be about to glean whether the provider is a "balls to wall" type of gal, or a take it slow, this is "all about you" type of escort.

I've had one Lady tell me she undresses herself quickly so some ham fisted guy does not wreck her delicates...  although the same lady has no qualms about undressing me.  I'm like to undress her out of street clothes some day.  
I agree a bit of flirting / naughty teasing is a turn on and if you are a one shot guy, makes the buildup more enjoyable.  
Perhaps there is a bit of laziness to it...  an unspoken "hurry up".  So she has to work less.

If I don't know what you are hoping for, I tend to dress in some sexy lingerie and if I'm at my incall, I cover it in a silky bathrobe. I always ask if you have a special request, and being fully dressed at the beginning of our time together would qualify as special request! I'm not a mind reader but can definitely be sensual and slow instead of sexy and spirited.

Communication is key.

I have to admit...

I am one to quickly strip down, usually to work up a quick warm up massage of each other so we can get the chemistry going rather quickly, sexually. I have thought about the meticulous disrobing of each other and I can see the value added of this in the gfe. Guess it depends on how horny you are, eh?
