Check out this article about the most ridiculously obvious sex studies of 2007. An excerpt:
People like to have sex for all sorts of reasons. So should it be any surprise that, when asked to give 237 possible reasons for putting out, the most common responses from college students included: wanting to experience physical pleasure; being attracted to their lover; or just simply sex feels good?
Perhaps the tragic bit about these findings is that researchers at the University of Texas spent five years and their own money confirming these ridiculously obvious motivations for wanting to knock boots.
Hopefully 2008 will yield a breakthrough study about the healing powers of YouPorn.
