Oral Exam: What is the Kivin Method?
According to Sex with Emily, there are a few techniques to master with your hands for this move. With your left hand, place your index finger and thumb on either side of the clitoris to raise it and help keep it in place while you lick. Communicate verbally with your partner as to what finger positioning feels best for them, and adjust accordingly.
Some people who have tried this method claim that once the clitoris is aroused, they can feel two small bumps on either side of the clitoral hood, which feel like two small grains of rice. These are called “K points”. If you are able to feel them, sweep your tongue over the clitoral hood in between these two points.
Remember that the clitoral tissue swells when aroused, just as a penis does. So, if you’re unable to find them at first, stay curious and you might notice these bumps become more apparent during the experience. Of course, everyone’s genitals are unique, and some may not have detectable “K points”. Don’t worry too much if you can’t find them, it’s more important to listen to your partners verbal and physical feedback anyway.

With the left hand, the giver also needs to place the middle finger on the perineum (the area between the vagina and the anus) to feel for muscle contractions. As you feel your partner nearing orgasm, begin to concentrate on the head of the clitoris with the tongue.
