If you're a fan of not having a limp penis, you might want to turn up your coffee drinking habits.

According to a study posted in the PLOS ONE journal, drinking two to three cups of coffee a day significantly reduces your chances of getting erectile dysfunction.

The study asked 3,700 men questions about their diet, exercise habits, alcohol and caffeine intake. From that data, they concluded that the dudes that drank 85-170 mg of caffeine, which equals about two to three cups of coffee, were 42 percent less likely to get erectile dysfunction.

Researchers believed the reason for these results was that caffeine affects the way our blood vessels function, and caffeine helps the blood flow to the penis.

Even crazier, the results were the same for those who were obese, and those who had high blood pressure. The only visible exception was to the subjects with diabetes, as diabetes is known to be one of the strongest deterrents to erections.

So, guys, invest in a good coffee machine, or keep loading up that Starbucks card, unless you're content with the flaccid life.
