Feeling stressed? Taking on lots of new commitments? If you answered yes to those two questions, you may need to take a close look at your love life, according to a team of German researchers.

That sex reduces stress -- or that no sex increases stress -- is hardly a new observation. A team of German researchers, though, is arguing that sexual frustration is a complex phenomenon not to be underestimated. It can precipitate a downward spiral, pulling couples helplessly and unbeknownst into a swirling vortex of all work and no nookie.

Ragnar Beer of the University of Göttingen surveyed almost 32,000 men and women for his Theratalk Project, which has found that the less sex you have, the more work you seek. Indeed, the sexually deprived have to find outlets for their frustrations: they often take on more commitments and work.

Appearing neither stressed nor over-worked, these people seem to support Beer's theory.
