It's been noted that, just perhaps, members of the male gender haven't fully grasped the essential techniques of the wondrous sexual act known as cunnilingus. I will endeavor to use my decades of experience with hundreds if not tens of thousands of satisfied women (some of whom had to undergo physical therapy afterwards to regain proper use of their orgasm-weakened legs) to help those poor unenlightened men throughout the world.
Of course, some of you do not need this advice. For those of you I say, good men!! The rest of us hate you, of course, and tell women behind your backs that you are actually nice, Church-going guys who'll care for them and listen to them just to make sure that you never again in your lives see live poonage. We're guys. What can we say?
First, the act of cunnilingus should not be undertaken without some preparation. Proper physical preparation includes basic stretching exercises, especially the neck which will receive certain abuse by being yanked about mercilessly during the act. Other preparation involves breathing exercised designed to increase lung-capacity. Women, for reasons unknown, tend to hold a man's face into their nether regions during cunnilingus much as a mafia hit-man might hold a victim's face in a swimming pool - until they stop wriggling. Dying during cunnilingus is considered gauche in polite circles no matter how legendary it may make you inside countless frat houses.
Second, a man should never proceed directly into cunnilingus. There is a concept known as foreplay which should always be undertaken. Contrary to popular belief, foreplay does not consist of kissing her, smacking her ass, and saying "You wet yet, baby?". This is also considered gauche and may get you shivved. You should take some amount of time in kissing her and caressing her back and arms gently, proceeding to her legs. Take your time. It's not as if you have an Academy Award ceremony to attend. You don't have anything in the microwave. Take your time. Your patience will be rewarded.
Once you have given her the proper amount of foreplay, she will give you subtle hints that she is ready for more intimate attention. She may do such things as guide your hand to more intimate areas or take your genitals in her hand and softly say "If you don't lick my pussy, I'll squeeze these things into pate". For some reason, this is not considered gauche. Do not try to question her at this point. She is a woman on the edge of either satisfaction or homicide.
Third, move swiftly and unhesitatingly toward her genitalia. Kiss the insie of her thighs gently. Nip them softly with your teeth. Again, should she take vise-like hold of your testicles, feel free to move straight to the vagina. Use your tongue as a master artist might use a paintbrush to paint a delicate landscape. Run your tongue up and down her vagina slowly and gently, to increase her desire (again, paying close attention to any sudden and possibly felonious moves she might make to hasten you along). Part her labia with your fingertips (taking care not to use your fingernails. Try scratching your nails along your own penis. Go ahead - I'll wait until you've stopped weeping) and gently dart your tongue into the succulent inner folds. Taste her as you would the sweetest ambrosia, regardless of whether it's ambrosia there or not. Women are like wine: Some have a piquant and insouciant taste. Some are seasoned and spicy. A rare few taste of old dishwater. Suck it up, men, and get your tongue in there.
