Studies show that women can “think” their way to orgasm. In other words, have ‘mental’ orgasms without touching their genitals.  The physiological responses of blood pressure, heart rate, and the dilation of the pupils as well as the insensitivity to pain during orgasm were measured in women who think their way to orgasm.  The results were compared to the physiological responses of women whose genitals are stimulated to orgasm and the results were comparable. Fascinating research.  Check out this youtube video for more details.
