From Women's Health Magazine: "These bliss-inducing muscle contractions can explode spontaneously during one sexual encounter, but at other times they require a superspecific setting (soft music, dimmed lights), body position (half pike with a twist), and technique (clockwise clitoral stimulation, please!) to set them off. And hitting the height of pleasure is no guarantee."
