A woman needs a continuous flow of stimulation in bed to get an orgasm. It is the best method for bringing her to orgasm. When you sense that she's about to come, don't stop and don't make changes. Keep doing whatever you're doing faster and harder to bring her over the edge. For the same reason, when you go down on a woman, the technique of "the alphabet" (licking her in the shape of all letters from A to Z) is DUMB - even though it's often recommended in magazines or on TV. It doesn't work because you keep doing something different - A, B, C etc. Instead, you should be doing it in a way that you see she enjoys, and keep repeating the same motion. Always remember she needs a Continuous Flow of Stimulation to take her pleasure to the next level.
