It's obvious that both sexes need lessons on how to perform oral sex.
Women would do well to read, consider and analyse this post by @SwitchableSusie.

What she says there is absolutely correct. Don't simply skim through it and move on, but spend some time thinking about what it really means, and how you can make use of it.
I'm certainly qualified to say that some women are better than others in the art of giving oral sex. Some do see it as a chore, and aren't genuinely interested in becoming any better at it. Some do actually try, but have no clue about technique. They keep changing what they do every few seconds and therefore fail to maintain the stimulation necessary. There are others who don't listen to you when you give them directions as to what you like. While not actually telling you so in words, this type have the attitude that says, "This is how I do it, and if it doesn't work for you, it's your problem".
Wrong.
* Be prepared to learn. Nobody knows everything, especially with closed minds
* Be prepared to listen to your partner. What feedback are you getting, and are you adapting what you do accordingly?
* Do think back over your own performance and be honest with yourself about what worked, and what didn't work quite so well
The recipient should give feedback. Whether or not you like something will to an extent be obvious. But if she is doing things right, tell her. If you want her to do something a little differently, tell her.
The same advice pretty much applies to men when giving oral sex to women. From what I've heard and been told by women, some men are better than others. Be self-critical and improve.
