Is something slowing down your sex life?

One episode of sex lasting 20 to 30 minutes can burn 300 calories -- the equivalent of running 3 miles. But the usual episode of 2 to 6 minutes uses only 25 calories (a quarter of a mile). If you cannot walk up and down two flights of stairs without stopping, it's a sign that you've got a problem that most likely will affect your sex life. Get fitter -- and friskier -- with fast walks, daily swims, and other on-the-move activities.

Maintaining the health of your sex organs not only ensures longevity but also supports a rich and fulfilling life. Above all, the most important thing you can do is follow the RealAge guidelines for decreasing arterial aging: Exercise regularly, eat a heart-healthy diet, and reduce stress. That will ensure a clear and well-flowing vascular system that promotes blood circulation to every part of your body -- including your love muscles. In fact, maintaining good blood flow is one of the best ways to make sure erectile dysfunction isn't inevitable as you age.

Just a few simple changes may be all that's needed to keep your sex organs in tip-top condition.
