What is the protocol asking a respectable reviewed provider about if she has had a recent STD test, is it even allowed? I figure between you business and private life you ladies are at higher risk to contract them. How often do you get them?

Is it "allowed"?
Well I suppose it's not against any written rule.

Is it rude and pointless?
Absolutely yes.

Besides, do you really think you'd get the absolute truth? You probably just want to hear something to make you feel better.
If you're that worried about it, find another hobby.

Just sayin'

...contract and spread diseases than younger college types or females from destitute countries.

An experienced provider has adopted well-established sexual habits, making the less experienced indulger excellent candidates for prevention efforts.

Ever use Google?

Geez...
