How I wish that medical researchers would do double blinds on these topics so important to sexual bliss.

The late comic Sam Kenison (sp?) talked of doing DATY through the alphabet, starting however with "O".
Girlfriends and wives howl with lust and say: "Oh my God, you must be French!"

You TER members surely include a few connoisseurs of exquisite daty who make your partners leap into the ceiling.

Tell us how you do it, and the kinds of results you get.
Which letters are the most difficult?
Does it work as well with Chinese or Japanese characters, or those exotic European alphabets in Czech Rep or Russia?

If a vix said: "Ommagod, you must be Lithuanian!" Should I laugh, or switch to French and try to go through a Camus novel with her?

Remember that most providers are very good at faking it in general -- and that is particularly the case when you are DATY.  It's actually pretty easy to tell if they are faking it if you have ever actually DATY with a non-provider to completion.  My W and I do it, for example, to completion -- and it takes quite longer than a provider might pretend with you that it does (after all she is trying to keep things moving along) and is more intense.  If you want to tell the difference, focus on her breathing (it should get longer and deeper, not quicker and shallower) and the tension in her muscles (her muscles will likely tense, esp the legs).  So, DATY technique with providers seems less important (at least to me) -- for the most part, they are going to react in a more or less scripted way regardless of what you are doing.  Sure, if you have a good technique, give it a try, it will be more fun for you anyway -- but don't fool yourself into thinking that her reaction will be much different from what it would be if you were using a less well-developed technique.  

I know that many hobbyists really like to think that the provider is aroused and into it (and in some relatively rare cases she may be) -- and I guess that's why some providers spend so much effort trying to fake arousal -- but I would think it must be irritating to providers after a while.  I mean, as long as the hobbyist is into it and is enjoying it, and the provider is participating actively (and not simply lying there, etc.), why does it matter if she is really aroused or not?  It must be really irritating for the provider to be put under this kind of pressure from numerous hobbyists, but that's just my $0.02.

If the provider has your head in a vice using their legs and/or hands then your DATY technique is good.

Not all providers are faking it. Sure sometimes the technique is not the best (that's when some hardcore fantasies help), however if it is not working, then we either switch to something else or I give a bit of heads up on what I like.
What I have found to be amazing in my experiences is that when I was younger, I used to think the hunks would make the best lovers when in fact it's the common looking guy, teddy bear or larger than average guy who tends to be the best lovers.  
I think for providers, it's all a state of mind.  If it's just business to get over with, more than likely that will be how your body feels as you go through the process, however with myself, before going into the situation, I like to take some time and think some sensual thoughts or sometimes naughty, depending on my mood and get myself into a certain state of mind so by the time I get there, I am wanting to be relieved

I like your mental prep!

Is it easier to get yourself in that "certain state" on a repeat date?

Definately easier cause now I have something to focus on.  I guess for myself I don't get all hung up on those wash board abs and such and I just try to remember something that he did that felt oh so good and go from there

I read one article many years ago in one of those sexology publications that really made me feel better about my sexual side.  

Having always been less that fit and trim. I not only had tough times as a teen in the dating department, but developed a sense of being undesirable sexually.  Well as years passed I got my chances and found that my partners liked the oral and manual attention I gave them even if I wasn't the best guy to have lying on top of them in mish.

Then I found the article.  It essentially said that guys who are over weight have developed a need to please because of the relative lack of attention paid to them by the opposite sex when compared to the jock types.  This makes them the best and most giving lovers. The jocks, on the otherhand, have come to think of themselves a desirable based on the social attention paid to them.  They tend to be more self-centered in lovmaking and therefore do not focus on pleasing their partners physically because they feel that their just being there is enough of a thrill.

There was much more said about the psychological process behind this but that was the take home message.

I'll never forget the time I actually beat out one of my more studly friends for the affection of a lady with whom we had both had the pleasure.  He just couldn't understand how she could possibly make the choice to accept dates with him to places where she could be seen in public (and spend his $), but I was the one to was spending the nights in her bed.

There used to be a show on cable called "The Man Show", late night, based on the premise that all men like to guzzle beer and watch busty vixens jumping on trampolines.  I normally didn't watch this show, but surfing one night, they had a 40ish female "sexologist" as a guest who was there to instruct us guys on proper technique for cunnilingus, half serious, half tongue - in -cheek. Before you start posting, I don't know how to do it with my tongue in my cheek, so don't ask!

She described the appropriate motions as actually creating the alphabet with your tongue, the point being, I guess, that the changes in movement, speed, pressure, etc. was what gets a woman off.  Also paying attention to all anatomical areas, and not just zeroing in on one spot.  Having tried this approach, starting with the letter A, it still varies from woman to woman, but it is a good starting point because going through some sort of excercise like this may allow you to find one or two things that do excite her more than others, and then you can adjust your approach.  

You can use any alphabet you want, Arabic (ours), Hebrew, Cyrillic, Chinese.  I like International Morse Code. LOL.

BTW, the second part of this show was on how to find the G-Spot, which included a set designed to look like the interior of a vagina, complete with one of the guys walking around inside, wearing a miner's helmet complete with lantern.  It was really funny.

What you describe has totally been my experience. Overweight men tend to be attentive lovers.
