75 percent people gave their feet the lowest, zero rating - alongside knee caps, the Observer reported.
Professor Oliver Turnbull of Bangor University's School of Psychology and the scientists from the University of the Witwatersrand in Johannesburg saw that there were 'remarkable levels of correlation' between the ratings for all the people who responded.
Men and women listed the 41 body parts they were asked to rate in remarkably similar order.
The obvious bits of genitalia were at the top of the rankings, as were lips, ears and inner thighs, followed closely by shoulder blades.
There were a few major differences between the sexes - the back of the leg was barely acknowledged by women, for instance, while men rated it as important as their ears. Hands were also more erotic for men than for women, researchers found.
