At Liberty Log, fellow Michiganian Chris Pellerito notes:

Speaking of Reuters, they also report that the US is the world's sexual superpower. This claim is based entirely on poll data, in which nobody has any incentive to tell the truth. This point is so totally lost on Reuters that they diligently report:

"Men appeared to be more sexually active than women, claiming a frequency of 102 times a year against 91."

Somebody explain to me how that is possible ...

Well, possibility one is that, as Chris noted, they're being a little parsimonious with the truth, as men have a wont to be in matters sexual ("Really, honey, that is eight inches...Really, honey, I can readily survive for over five minutes without breathing through either my nose or mouth...").

Possibility two is that the male/female ratio in some of the reported encounters was something other than one to one.

Possibility three (also highly likely) is that the number of partners for men is not necessarily the same as the number of partners for women.

Possibility four is that not all of the encounters were heterosexual.

Possibility five (almost certainly the most likely) is some combination of all of the above.

Bottom line--don't try to draw any conclusions, useful or otherwise, from sex surveys...
