"And the prettiest foot! Oh, if a man could but fasten his eyes to her feet, as they steal in and out, and play at bo-peep under her petticoats!"
—William Congreve (1670-1729),Love for Love.

Throughout time and across cultures, the foot has been a focus of sexual yearning, and none of us seems to know why. Podophilia, or "foot lust," is the desire to caress, kiss, bite, lick, fondle or have sex with a foot. The podophile (not to be confused with pedophile, or paedophile) looks on the foot as a sexual object, focusing on the skin texture and color; shape of the instep, toes and heel; and especially the smell. Open-design footwear, such as high-heeled sandals, are particularly evocative. These fetishists experience the highest level of arousal and orgasm from pedal love-making, whether as foreplay or as actual "intercourse."
