I was doing research for the book (Bondassage For Lovers) yesterday and I found out about Primary, Secondary and Tertiary erogenous zones.

PRIMARY Erogenous Zones (2)(4)
*the mouth
*the breast and nipples
*the genitals

SECONDARY erogenous zones  (1)
*the earlobes
*the nape of the neck
*the inside of the thigh
*the base of the spine
*the gluteal fold where the buttock meets the top of the thigh

TERTIARY erogenous zones (3)
*the outside surface of the little finger
*the center of the palm
*the nostrils
*the car canal
*the sole of the foot
*the big toe
*the back of the knee
*the navel
*the anus

According to classical Indian sexual practice, the most effective way to stimulate these erogenous zones is in a 4-beat pattern:  first the secondary zones, then the primary zones (but not the genitals), then the tertiary zones, then back to the primary zones.
