True, although in this case I doubt the people who run that site actually funded an in-depth research project into which genes correspond to which masturbatory preference in different genders (which is not to say that there isn't some uni or other doing exactly that right this moment).
至 paulmeep :Well, much research isn't surprising. I don't find it surprising genetic differences explain part of how different humans process altruism, although if you're an evangelical equalist, you might not open your eyes and realize it. Having the specific alleles is just gravy
Women seem to be much more bi-oriented than men, this (pornsite...) research seems to corroborate that.
