By lovely I mean the one who is considerate. The one who booked you in a respectful way. The one who is fun to be with. The one who may not be "your type" but you enjoy seeing. Maybe it's also the one with a huge tip, but maybe not.  

I can usually tell from an introduction email if I'd like to have someone as a client. I adore respectful & informative introduction emails. It shows me you're serious about spending time with me. Being respectful, punctual, and considerate goes such a long way and automatically puts me at ease, which in turn puts you at ease...

Everyone says they want to see the perfect gentleman with good hygiene and all that. I think all those things, for men and women, go without saying.  To me, my AFTs treat me like a real woman. The intimacy is always great but to me it is taken to the next level when they take the time to talk to me as a human, not just a vessel to appease their physical needs.  

I have had days when I want to get down on my knees and say "thank you!" for fellows like that.  All providers know that our lives have particular difficulties.   Real gentlemen?  I love them.  

something small but important about myself in an intro once and never heard back from her.  All I said was please don't touch my ass because I'm having a hemorrhoid flare-up right now.  So I have to disagree with you on that one point.  

...no man with an once of self respect wants to be called "lovely". SMH.  

(Animal House references for you youngsters out there....)

I would actually like to see that- a total BFE male provider, indulging our vanities, rubbing our feet, eatin' the pussy, hanging on our every word like what we said was the most intelligent thing in the world.
A provider so good at hittin' it, that we just gotta brag to all our girlfriends about him.
Washed balls, trimmed pubic hair, always on call, and up for anything.
Yep...
I'd love t see that, website & all.

(Except tipping... I'll echo the platitude that the best tip is a repeat date. I rarely ever get a cash tip and sort of feel funny when someone gives me one).  

Not only does it show that he's serious, a great intro email (along with a pleasant, stress-free pre-date correspondence) will help me look forward to the date. Like, 'Hey, this guy sounds cool!'  

While I have no doubt based on the totality of your posts, but especially this one,I'd love to see you... I ALSO have no doubt I'd NEVER want to see you right after him  

I consider myself a lucky lady. My screening can be a pain at times; but I want to make sure that I will meet with a truly gentleman. I have many great clients / friends. I enjoy a good conversation, a respectful encounter, someone that is clean and smells good, someone that respect my boundaries and I always repeat the same thing over and over again... "someone that doesn't treat our date as a fitness competition". There's no need to prove certain abilities.. it's all about explore, fantasize, have fun and go with the flow.  

"fitness competition" ha ha  

I try my best to remember details that they have told me in the past and try to keep it more like we are friends getting together to enjoy each other's company.  Some you connect quicker then others.  You sound wonderful already most likely you don't need to change a thing, and thanks for being so considerate.  

In my opinion, the best clients are the ones that love DATY which seems to be pretty common so I'm very happy :p also cuddles and light convo after -  you know. All my clients have been easy to talk to, respectful of boundaries, clean and eager to please me also which is a nice surprise.

Then I wipe my dick on her drapes.  I'm nothing if not classy.

They're like sugar babies. Usually only rich old ladies bother. Regular ladies can get it for free.

The obvious is to not contact ladies who aren't what you're looking for, expecting something different. (Price, location, look, screening requirements, etc)

that's because they watch too much porn

that's what drapes are for

Do you prefer your clients to be well-endowed, or is DATY enough to satisfy you?

Get acquainted with the information she has online - websites, ads, etc. Be thorough and take in the information she chose to make available.

you'll have a sudden uptick in business.  
DATY lovers love to hear that ...

Obviously the more the better, but just curious, in your personal opinion, where's the line for

DATY can definitely be enough. This one client went on for about an hour and I was thoroughly exhausted after that :p

A client who by the first communication, you can just tell he is respectful and interested in also participating to make our session mutually enjoyable. He makes the screening process a breeze and has picked a rendezvous a few days in advance to allow for enough time for me to check out his reputation. If a deposit is necessary he sends it, sometimes I have gentlemen send more than what is required of them, I guess it is just to show their sincerity, and I appreciate the touch.
They confirm and respond the day before our date. If it is an outcall booking 2 hours or more, they offer to spend time munching on room service incase I'm hungry. These little touches, bounce someone to the top of my list. None of it is required in order to have an amazing time, but it makes for a very nice memory.

We do love to hear that.  mmmmmmmmmmmmm DATY ...

To be a great client!

I will fawn all over a 15$ tip if I know it was hard for the guy to break his wallet open again (some save up for the experience, and I always respect that.)
But start at 50 and work your way up from there is a good rule of thumb, I also like it better when a guy doesn't draw a huge amount of attention to it, maybe just place it on top of the envelope without saying anything. At the door with a kiss goodbye, putting it into my hand w/o saying the amount, that's a good one too.

Everything you suggest sounds totally reasonable and pretty close to common sense.. It's just a bit too bad that obviously some clients don't know/care about this stuff.

lol.... love it, though most seem a bit young. Maybe rub a bit of engine oil on them, place a few years in their eyes and a book in their hands, or a pic of them working on a car engine- then almost perfect.
