I'm pretty sure those athlete sex reports are highly exaggerated. Those numbers are based on a ridiculous calculation where they took the number of condoms shipped to the Olympics and divided it by the number of athletes.
Exaggerated in one way, possibly under-reporting in another. What if athlete sexual activity follows a power law? A very small number of athletes might have hundreds of hookups during the games while most may have zero or one.
You think it's just a few athletes having lots of sex? No wonder they are so fit!
I think they are forgetting all the people visiting the city for the olympics that aren't competing in their numbers.
Actually these stories are generally talking about the number of condoms available to the athletes in the athletes 'village'. But generally the condoms are branded for the event (like everything else) and hance are souvenired in large numbers distorting any estimates of athlete nookie.
