1. Exercise. After studying more than 31,000 men, the Harvard School of Public Health concluded that those who exercised had a 30 percent lower risk for erectile dysfunction than those who didn't.

2. Eat Right. Make sure you eat lots of fruits and vegetables, lean meat, and foods high in anti-oxidants.

3. Do Kegel Exercises. These strengthen the pelvic muscles. An easy way to identify your pelvic muscle is to stop the flow of urine midstream. That is pretty much what you will be doing when you do a kegel exercise (without peeing, of course!). Contract this muscle and release as many times as you can.

4. Take an herbal sex supplement. I recommend a supplement called Zenerx because it contains all the ingredients you need and there are no side effects. The herbs in Zenerx have been used for centuries by people around the world to boost their sexual performance. And there is a growing body of scientific evidence that these herbs really do work.
