Can't perform the calculation
When I went to do the test and entered my age and the number of partners (over 50) the calculator announced it couldn't do the calculation.
Made me feel quite the stud.
It would be interesting to see the algorithm. It would have to weight the average number of encounters for each partner since the highly promiscous are likely to have more sex with the highly promiscous than others, and also whether the encounters were homo or heterosexual (and discount the figures for the number of sheep shagged).
