I'll bite.
In my book-- your 4 A's are pretty accurate.
Attractive-- This one is possibly the most subjective-- because everyone has different tastes. Talking about myself personally-- I'm in the camp of girls who are "cute". Meaning-- I'm reasonably attractive, but I'm not the sort who turns a lot of heads in public. Which honestly-- is fine by me. I do what I can to put forth effort-- I'm never going to open the door in sweats with no makeup or messy hair. Honestly-- a 5 can turn into a 7 or 8 real quick with just a little effort.
Affectionate-- This is one that will vary wildly. Surprisingly, some gents do NOT want an affectionate provider. I have turned down gents in the past because they've said they don't like to kiss and well.. that's a must for me personally.
Attentive-- This should be a baseline-- PUT DOWN THE FUCKING PHONE. Even those of you who like to say $$ is for time only-- well cool, he's paying for an hour of your time. Its his hour-- put down the phone.
Appreciative-- And this right here-- this is where I've built my business. I don't demand "extras" from my gents. Tips and gifts are always sweet-- but their presence is my present. The best compliment a gent can give is coming back over and over again.
At the end of the day-- most gents in the hobby just want a little carved out time where they get to be spoiled an appreciated.
Having said all this-- you can get all of these things from a range of 300-800 or more. And unfortunately, you could also pay 300-800 or more and get none of them.
The reality is-- some gents will never play over a certain price point. Some gents will never play under a certain price point. But most are somewhere in the middle. They try to stay within a range, but will occasionally splurge if all the planets seem to align.
