Do Men and Women Cheat for Different Reason?
If you're exposed to any form of American media, you may think that everyone is having an affair. The news is full of celebrities, athletes and politicians caught with someone other than their spouses. In prime time, you can watch the Desperate Housewives commit adultery, then flip the channel and find the Mad Men doing the same thing. Romance novels feature illicit trysts, and much of country music would have gone unwritten without someone's cheatin' heart.
Is infidelity the norm? Scientists know of only a few species that are completely sexually monogamous; one such species is the Diplozoon paradoxum, a flatworm that fuses to its partner until its death [source: Angier]. Even in animal species that practice social monogamy, such as birds that raise their broods in pairs, sexual monogamy is not the norm. A male bird may be raising a brood in which 10 to 30 percent of the offspring aren't his own [source: Barash].
But here's one case in which humans aren't emulating the birds and the (assumedly frisky) bees.

And while the existence of true natural aphrodisiacs is up for debate, it's an absolute fact that eating certain foods can and does improve your overall sex life.

True, most of these foods are useful for their nutritional value -- it's obvious that someone who gets a diverse mix of fruits, vegetables and fiber in his or her diet is going to be more capable in bed. But there's a set of nutrients your body uses specifically for sex. We'll look at 10 of these nutrient-rich foods that help keep you ready for action when the lights go out.
