And what you talk about in he last paragraph I’d say is a whole different dynamic (and a fun one!) that is not so much about what you are doing as to why you are doing it.

Yes!

“My mission is to turn my lips, my tongue, my hands, my throat, my larynx, into a chimeral machine of pleasure. This is not the time to make it about me.”

No! At least in my opinion. If you invented a machine that produced the same physical sensations as a great blowjob, it wouldn’t hold a candle to an the most unskilled blowjob that was that was over way too soon as long as the unskilled one had enthusiasm. What it’s really all about to me is a long, enthusiastic kiss for the cock. It says, “I love you and your cock. Not just your sense of humor, loyalty, intelligence, eyes, whatever. I love your cock.” The eye contact expresses the difference between that and “I’ll do this for you but don’t expect me to like it.” This is also why continuing through orgasm is a big deal, it’s not because switching to hands is few seconds of a lesser sensation, it’s because switching says “Get that nasty crap away from me.”

I love this blowjob Flash animation because of the expressions and eye contact, despite the lack of actual sensation. About as NSFW as can be.

I get the feeling that for my wife cunnilingus has more sensation and less sentiment involved. I play up the loving the pussy aspect which she enjoys but not as much as I do when it’s the other way around.
