Key Facts
- ED is defined by a consistent inability to get or keep an erection firm enough for sex. A single bad night is not ED.
- Symptoms include erections that are too soft, don’t last long enough, or are difficult to achieve in the first place.
- ED is not the same as having a low sex drive (libido) or issues with ejaculation.
- Often, ED can be an early warning sign for other health problems, particularly heart disease and diabetes.
- If these symptoms sound familiar, it’s a sign you should have a conversation with your doctor.

One Bad Night vs. A Consistent Problem
In my line of work, I have this conversation almost every day. A man sits down, a little hesitant, and says, “Doc, I think I might have ED.” The first thing I always do is ask, “Tell me what’s been happening.” Because the most important word in the definition of erectile dysfunction is consistent.
Every man, at some point in his life, will have trouble with an erection. Stress, fatigue, too much alcohol—these are all normal life events that can temporarily interfere. That’s like your car failing to start once on a cold morning. Erectile dysfunction is when the car consistently fails to start, week after week. If you’re experiencing issues more than 50% of the time you attempt intercourse, then we’re in the territory of ED.
The Core Symptoms of ED
ED isn’t just one single thing. It can show up in several different ways. See if any of these sound familiar:
- Trouble Getting an Erection: You’re aroused and you want to have sex, but your body just doesn’t respond. The signal isn’t getting through, or the blood flow isn’t sufficient to get things started.
- Trouble Keeping an Erection: This is very common. You might get an erection, but it fades too quickly, sometimes before or shortly after penetration.
- Erections That Aren’t Firm Enough: You can achieve an erection, but it’s too soft for satisfying intercourse. An erection needs to be rigid enough for penetration, and if it’s not, that’s a key sign of ED.
- Unsatisfactory Intercourse: Sometimes the mechanics are there, but the experience just isn’t satisfying due to the anxiety or difficulty surrounding the erection. This psychological component is a very real part of the condition.
Common Mix-Ups: What ED Is Not
Men often lump several different sexual health issues together. It’s crucial to separate them so we can find the right treatment. Here’s a quick guide to what ED is not.
| The Issue | What It Is | Is It ED? |
|---|---|---|
| Low Libido | You have a lack of interest in sex. The desire or drive just isn’t there. | No. ED is a problem with plumbing (blood flow), not desire. You can have a strong libido and still have ED. |
| Premature Ejaculation | You ejaculate much sooner than you or your partner would like during sex. | No. This is a problem with the timing of ejaculation, not the erection itself. |
| Delayed Ejaculation | You have difficulty reaching orgasm and ejaculating, even with a firm erection. | No. Again, this is an issue with ejaculation, not the erection. |
It is possible, of course, to have ED alongside one of these other conditions, which is why a conversation with a doctor is so important to get to the root of the problem.
Why ED Can Be Your Body’s “Check Engine” Light
This is the most critical point I can make: erectile dysfunction is not just a quality-of-life issue. It is often the very first sign of an underlying, more serious health problem. I tell my patients to think of an erection as a sensitive barometer for a man’s overall cardiovascular health.
The blood vessels in the penis are much smaller than the ones in the heart or brain. If they are starting to get clogged or damaged by conditions like high blood pressure, high cholesterol, or early-stage diabetes, the first place you’ll see a problem is with your erections. For many men, ED is the “check engine” light that tells us we need to look under the hood. By addressing your ED, you may also be taking steps to prevent a future heart attack or stroke.
So, if the symptoms I’ve described resonate with you, don’t ignore them. It’s not just about sex—it’s about your health. The good news is that we have many effective ways to treat erectile dysfunction, and starting that conversation is the first step.
