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.
