Usually a mix. Anxiety, stress and relationship tension on one side; erection problems, the prostate, the thyroid, a very sensitive penis or a medication on the other; and, in my view, habits. If it appeared recently, a physical cause is more likely, so see a doctor first.
For years I thought I was just built wrong. I finished too fast, I didn’t know why, and the only explanation I could come up with was that this was simply how I was. I never talked about it with anyone, so nobody could tell me otherwise.
Looking back, I think not understanding where it came from hurt almost as much as the problem itself. When you don’t know why something happens to you, you fill the gap with whatever crosses your mind, and it’s rarely flattering.
So here’s what I wish I’d read back then: what doctors say about the causes of premature ejaculation, and what I worked out on my side.
What causes premature ejaculation?
The short answer is that there isn’t one single cause. Urologists separate psychological causes (performance anxiety, stress, tension in the relationship) from physical ones (an erection problem, an inflamed prostate, a hormonal issue, a very sensitive penis). In a lot of men several factors mix together, and the habits your body has picked up play a big part.
That sounds vague, but it’s actually good news: it means there’s more than one way in.
| Kind of cause | Examples | See a doctor if |
|---|---|---|
| Psychological | Performance anxiety, stress, relationship tension, low mood | It weighs on your mood, or the anxiety spills into the rest of your life |
| Physical | Erection problem, inflamed prostate, thyroid or other hormonal imbalance, very sensitive penis, starting or stopping a medication or drug | It’s recent, or comes with erection trouble, pain, urinary symptoms, palpitations or weight loss |
| Habit (my own view) | Years of finishing fast without paying attention to arousal | Usually no need, unless one of the signs above applies |
The short version of this question has its own page: is premature ejaculation psychological or physical.
Has it always been there, or is it recent?
That’s the first question to ask yourself, because doctors draw a real line between the two.
There’s “lifelong” premature ejaculation, the kind you’ve had since your first time. That’s me: I’ve always had this problem. And there’s “acquired” premature ejaculation, which shows up in someone who never had trouble before.
To give you a rough idea, the ISSM (the International Society for Sexual Medicine) talks about lifelong premature ejaculation when it almost always happens within about a minute of penetration, while the American Urological Association (AUA) puts the line closer to two minutes. Either way, two other things have to be there too: the feeling that you can’t hold back, and the fact that it genuinely bothers you. The stopwatch alone isn’t enough to put a name on it.
Why does this matter? Because if it appeared suddenly, after a time when everything was fine, there’s a better chance of a physical cause behind it, and then a doctor should be your first stop. More in lifelong vs acquired premature ejaculation and why am I suddenly finishing faster.
Possible physical causes
I’m not a doctor, so I’ll stick to what serious sources list. According to the Cleveland Clinic and the American Academy of Family Physicians (AAFP), these include:
- an erection problem;
- an inflamed prostate;
- a thyroid problem or other hormonal imbalances;
- a penis that’s especially sensitive to stimulation;
- starting or stopping certain medications or drugs.
Worth knowing: when the two problems come together, the AUA recommends dealing with the erection first. And if any of these rings a bell, see a doctor before you try anything else. See is premature ejaculation the same as erectile dysfunction, is my penis too sensitive and should I see a doctor.
Anxiety, the fuel of the vicious circle
It’s the most frequently cited cause, and it’s the one I know best.
The mechanism is pretty simple once you’ve lived it. It happens once, then twice. You start thinking about it before, during and after. You have sex while repeating “don’t come too fast” in your head, and that little voice only adds stress, which speeds things up even more. And the more it happens, the more you stress.
I had my own version of this trap. When I knew I was going to have sex with my partner that evening, I’d think about it all day. I’d picture it, sometimes without noticing, sometimes on purpose. By the evening I was already so aroused that I came almost straight away. I’d done the whole climb in my head before we even started.
The numbers point the same way: according to data cited by the AUA, anxiety affects about 24% of men with premature ejaculation, against 13% of men without it. It’s hard to say which comes first, but each one feeds the other. More in can anxiety cause premature ejaculation and how to get over performance anxiety.
Habit, the cause nobody mentions
I’ve never read this one on a medical fact sheet. It’s my own opinion, so take it as such.
I think a good part of the problem comes from the way we learned to work. We often masturbate quickly, often in front of a screen, without ever paying attention to what’s going on in our body. And with a partner, our attention goes to the fear of coming too soon. At no point do we learn to feel arousal building, so at no point do we learn to slow it down.
What reassures me about this idea is that a habit can be changed. That’s what got me out of it, but it took me years, because I was searching in the dark. More in does masturbation cause premature ejaculation and why do I finish so fast.
What about porn?
I’m not going to tell you porn causes premature ejaculation. I haven’t found anything solid that shows it. What it does do is completely distort what we think “normal” sex looks like. What you see on screen is staged and edited.
When researchers asked couples in five countries to time themselves with a stopwatch, the median time from penetration to ejaculation was 5.4 minutes. If you compare yourself to a film, you’re comparing yourself to something that doesn’t exist. More in does porn cause premature ejaculation and how long should a man last in bed.
What knowing the cause changes
Understanding where it comes from doesn’t fix anything on its own, but it changes how you go about it. If it’s physical, a doctor can help. If it’s mostly anxiety and habit (which was my case), it can be trained, a bit like training for a sport. And often it’s a mix of both, which is exactly why urologists say combining approaches tends to work better than relying on one.
I go through the options that exist, what they’re really worth and what worked for me in the article on premature ejaculation treatments.
Either way, if you recognise yourself here, it isn’t your fault. You’re not “built wrong”. Your body picked up a habit, and your head started keeping watch instead of enjoying itself.
