If you’re asking this question, the odds are pretty good that you do have ED, according to MensHealth.com. It cites a study in which 1,000 men were asked if they had erectile dysfunction. That study, published in “BMC Urology,” revealed that 90 percent of men who claimed they were “unsure” suffered from at least some degree of this problem.
With normal erectile function, a man should be able to achieve and maintain an erection strong enough for intercourse. As he ages, it may be necessary to have more foreplay or self-manipulation to stimulate the penis, but erection should still be attainable. When it’s either difficult or impossible to get an erection or if an erection disappears before sexual activity is completed, it’s a pretty sure sign that you’re suffering from ED.
If these erectile difficulties occur only once in a great while and can be blamed on fatigue, too much to drink, or other temporary causes, it’s probably not a cause for panic.
