It turned out that, across genders, sexual orientations, and nationalities, everyone 
agreed that the genitals were top, followed by mouth/lips, with nipples, nape of neck and thighs also highly placed. The correlation coefficients for average ratings across pairs of groups were extremely high at 0.9 or above: people agreed with each other.
Agreement on the most unerogenous zones was also strong: these included the elbow, shin, knee-caps, nose, and forehead. Makes sense.
The level of agreement counts against the popular belief that men and women have substantially different erogenous zones. Though women did score a few areas – namely the highly ranked non-genital ones – more highly out of 10 than men.
