Results from the largest global study of sexual kinks ever undertaken show that feet and shoes are by far the biggest turn-ons.
Researchers from the University of Bologna found that, among sexual preferences for body parts, feet and toes were the most popular, with 47 per cent of those sampled preferring them. They also found that, when it came to objects associated with the body, shoes, boots and other footwear scored 64 per cent.
The survey, based on the views of men and women, also revealed some of the more obscure objects of affection. These included 150 people with a penchant for hearing aids, and two whose hearts go into overdrive thinking about pacemakers.
Some 12 per cent were turned on by underwear, 9 per cent by coats, body fluids and body size, 7 per cent by hair, 5 per cent by muscles, and 4 per cent by genitals and body modifications such as tattooing.
Three per cent cent went for navels, ethnicity and breasts, and 2 per cent for legs, buttocks, mouths, lips and teeth.
The lowest scores went to stethoscopes, wristwatches, bracelets, nappies and catheters. Body hair, nails, noses, ears, neck and body odour all scored less than 1 per cent.
