When a man suddenly finds himself unable to achieve an erection, panic sets in. After all, everything seemed a-okay downstairs yesterday, and yet, out of nowhere, your little guy won’t follow orders and stand at attention. Sure, this is the first time it’s happened, but one time is enough. You’re convinced you have erectile dysfunction, and you’re normally going to be able to achieve an erection normally again.

Okay, take a deep breath and take a step back. While erectile dysfunction can begin with an initial inability to achieve an erection, missing one erection should not be seen as the end of the world. If you’ve had an erectile incident and you’re worried that you may have ED, remember: Erectile dysfunction is defined as the reoccurring inability to achieve an erection.

Thus, one missed erection is not a sure sign that you’re dealing with erectile dysfunction. Though it’s not something you’ll hear your friends discussing in casual conversation, all men will experience an erectile issue at some point in their life. But it’s only when it becomes a repeated problem should there be cause for concern.

So, if you had an off night and found yourself struggling to achieve an erection, you can write it off as a bad night. But if it begins to happen consistently, speak to a doctor and together you can determine what is causing the issue.
