I am always very happy to learn as well as teach. Good communication is important. I appreciate a girl that can push all my buttons, so why not tell her (or show her) what they are? And vice versa. If I'm going to see a lady on a regular basis I absolutely want to learn about her body and what she enjoys. Finding out what your partner likes is half the fun. Her finding out what you like is the other half.
By the way, speaking of communication - I try and leave the whole "improving technique" bias out of it. I just simply say "this is what I like" and "what do you like?". It's straightforward and non-judgemental. On both sides. Besides, every girl I've known is different to some degree so I've never learned a universal technique that works on all of them. Hell, I haven't found one technique that works on the same woman all the time.
The best thing you can do is ask her what she likes, or better yet get her to show you (maybe with her favorite toy). It's fun, hot, and educational. Watch how she pleases herself and take mental notes. But probably the best skill you can ever learn is how to read female sexual body language. Then you can listen and watch for that arousal as you work your way up the excitation curve. Pretty soon you'll learn to play her like a Stradivarius.
While we're on the topic of toys - if a girl needs some assistance getting that elusive O and grabs a toy to help get the job done, I'm all for it. In fact, I think it's awesome. She knows her body better than anyone and if she needs that special toy, vibration, technique, or whatever to push her over the edge - why not use it?
If you play your cards right you'll have two winners in the "Beat the clock to the big O game."

I've had blow jobs that go on and on and on, but if she doesn't do it the way I like, she can't force me to cum. I'm always amazed at ladies that think hard, fast and forceful will make me cum no matter what, and they just go at it and at it.
I prefer for each lady to first show me HER technique with out my coaching; after all, she may teach me something. But once enough time has elapsed and I'm sure she's not going to get there on her own, I tell her what to do; which all but twice has yielded the desired result.
Oddly enough in this hobby, I've only had two ladies (so far) that really knew what they were doing, when giving a blow job. Changing tempo, rhythm, depth and technique until they figured out my combination. There were also two naturals, that did what they do, with out changing it up, but already did what I liked from the start. Judging from the lack of variety (and remember I lean more towards younger less experienced ladies) that many providers seem to employ, I would guess that there is very little coaching going on. My guess is that the hobbyists just take what they get and move on, and I suspect the lack of feedback makes it harder to collect new techniques.
I do have a fantasy though about getting a girl with some talent (i.e. she can go all the way down on me no problem and has no or low gag reflex) and teaching all the ways I've learned that a blow job can be given from my years of receiving from many different ladies and watching tons of porn. I'm confident I could train a lady to give a serious blow job . . . at least to me 
The ones that understand real head are Adriana Deville (tours around the US, home base in Miami) and the best head I've ever had was from Asian Molly (also in Miami), these ladies are artists. Asian Molly is my new standard for all blow jobs.
The two that just happened to do what I like: Aria at Mirage agency in Toronto and Asian Bea in Miami (formerly of Houston, and she passes through Atlanta a few times a year).
Now that you have me thinking about it, they all also are true PSE's and do greek and BBBJNQNS! These ladies are why I do this hobby. They are like that one shot on the golf course, when you've had enough and you're like fuck it why do I bother, and then bam a perfect shot exactly the way you planned it, and then you're hooked to play again.
Believe it or not, I actually prefer to please my partner and tend to her needs before mine.
I've always been a giver and derive more pleasure seeing my partner satisfied so I definitely love a lady that is honest with me. I hate the fake moans and fake orgasms. When a lady is open to communicating and instructs me on how to properly pleasure her, I find myself wanting to return especially if the chemistry is there.
So If a Lady wants to tell me how she likes things-bring it on. Cheers

I really enjoy pleasing as much as being pleased. Question to hobbiest- would you like your provider to let you know how to improve your techniques? And question to providers- do you give instructions on technique to your partners. (If they are willing)
I would like to hear from Providers too
I wouldn't call it "improving technique", because, well, different strokes for different folks. Pun totally intended. I feel like I'm a pretty intuitive lover, but I'm definitely not going to be offended if a man gives me an idea of what buttons he wants pushed. I'm all about the feel-good, so if there's something you really love and I haven't hit it yet, tell me. I'm down.
And for me? I know what I like. I've had a decent amount of sex in my life, so (especially during oral) I know what works for me. Hint : flat on my back, no pillows, with my legs up around your head. Boom. That doesn't mean don't taste me from another angle, or don't flip me into 69, it's all fun. But for the big finish, now you know.
Moral of the story, we're all different and most of us know what we like. Communication is always key, so speak up, boys. 
I have no problem telling a gentleman what turns me on :
