The mouth, lips and tongue are, of course, one of the body's premiere erogenous zones-something that's known to almost all the higher animals. During sex play, fish, lizards and most mammals will put their mouths on their partners' bodies, sometimes for hours at a time. A stallion mounting a mare will nibble, lick and snuffie her with his mouth and nose almost continuously. (Is it any wonder that in both humans and animals, the two most erotically sensitive places-mouth and genitals-have a habit of coming together during sexual encounters?)

In many men and women, the perineum-the skin between the anus and genitals, the place you'd make contact with if you straddled a fence post-is highly sensitive to touch. Dr. Kinsey found that "many males are quickly brought to erection when pressure is applied on the perineal surface at a point which is about midway between the anus and the scrotum." This rather secretive spot can be reached by direct pressure with a finger, through the rectum or (in women) by deep penetration of the vagina.
Earlobes become engorged with blood during sex, swelling and becoming increasingly sensitive to touch.

The thin skin on the inner surface ofthe thigh is richly endowed with nerves, and in some people stimulation of this area makes for an'especially arousing adventure. Other erogenous zones - all arousing to some people - include the throat, the armpits, the anus, the navel, the abdomen, the toes and who knows what else?

There may be others known only to your partner (or as yet unknown to him or her)-but you'll never find them until you set out ona Lewis and Clark expedition over the frontiers of your lover's flesh.
