“I can jerk off to porn and stay hard. But the second I try to have sex with my girlfriend, I lose my erection halfway through penetration. She thinks I don’t want her, and I feel broken.”
If that sounds familiar, you’re not alone. Thousands of young men in their 20s and 30s are writing versions of this on Reddit, Quora, and therapy forums in 2025. Healthy guys. Fit guys. Men who have no problem during masturbation but can’t keep an erection with a real partner.
This is called situational erectile dysfunction. It doesn’t mean your dick is broken, and it doesn’t mean you don’t love your partner. It means that your brain, your body, and your stress are out of sync when it comes to sex.
Situational ED shows up when a man can get an erection alone but struggles with a partner. Sometimes he loses it before penetration. Sometimes he goes soft halfway through sex. Sometimes he can’t get hard at all with a partner, even though masturbation is fine.
And here’s the most important truth: this doesn’t mean you’re weak, unmanly, or doomed to a lifetime of awkward, disappointing sex. Situational ED is reversible once you understand what’s driving it and most of the time, it’s more about your brain than your penis.
You can get hard watching porn. You can get hard when you’re touching yourself. But the second it’s real – skin-to-skin, with someone you actually care about, your erection disappears.
This is one of the most common stories I hear from men in their 20s and 30s. They describe:
On Reddit, one man put it bluntly:
“I can watch porn and cum without a problem. But when I try to fuck my girlfriend, I lose it before I even get inside. She thinks it’s her, but it’s my head messing with me.”
This isn’t a rare “problem case.” It’s situational erectile dysfunction. Your body is capable of erections, you’ve proven that alone. The issue is how your brain and nervous system react in a real sexual situation.
The truth is, erections aren’t just about blood flow. They’re about safety, confidence, and letting your body relax enough to allow penetration. When anxiety, stress, or porn-conditioning hijack the process, your penis isn’t failing you. Your nervous system is hitting the brakes.
Situational erectile dysfunction means you can get an erection in some situations, but not others. Most often, men describe being able to stay hard when they’re alone, masturbating, watching porn, or waking up with morning wood but losing it during sex with a partner.
This isn’t the same as chronic erectile dysfunction, where erections are unreliable across all situations. Situational ED usually shows up:
In younger men, this pattern is far more common than physical or medical ED. Studies show that in men under 30, most erection issues are psychogenic, meaning they come from anxiety, stress, or mental patterns, not from damaged blood vessels or hormones.
But here’s the key: situational ED feels just as real as chronic ED. The penis still won’t cooperate when it matters most. And because it shows up only during sex, it often feels more humiliating as if your body is “choosing” porn or masturbation over your partner.
The reality? Your body works. The erection problem is about context, not capacity. That’s why situational ED is highly reversible once you understand the triggers.
If you can get hard when you’re alone but not during sex with your partner, it’s not random. Situational erectile dysfunction happens because of specific triggers that mess with arousal in real time.
The second you start worrying about whether you’ll stay hard, your erection is already in danger. Sex shifts from pleasure to performance, and your nervous system pumps stress hormones instead of blood to your penis.
“The more I thought about losing it, the more I lost it. I was watching myself from the outside instead of being with her.” – Reddit user
Your brain adapts to endless novelty from porn, different bodies, categories, and kinks on demand. With a real partner, the stimulation is slower, more intimate, and less extreme.
This doesn’t mean you don’t want your partner. It means your arousal system has been conditioned for constant novelty, not real penetration and closeness.
Some men admit they can only stay hard if they imagine another person during sex. The guilt of “needing to think of someone else” raises anxiety, and erections collapse under that mental conflict.
Hookup culture and casual sex can create pressure to “perform on demand.” Some men stay hard with strangers but go soft with partners they care about. Emotional risk changes the way erections work.
Money pressure, job insecurity, and family conflict don’t disappear just because you’re in bed. If your brain is stuck in survival mode, it won’t let your body relax into sex.
One man put it bluntly:
“I wasn’t even thinking about sex, I was thinking about my bank account while trying to stay hard.”
Erections need energy. Late nights, long hours, endless scrolling, all of these drain your body. Even if you want penetration, your body may simply be too depleted to perform.
Paradoxically, ED often shows up with partners you love the most. You want to please her so badly that fear takes over. That pressure kills desire and makes arousal feel like a test instead of play.
The best way to understand situational ED is to hear it in men’s own words. These aren’t medical textbook cases, they’re raw, unfiltered, and painfully familiar if you’ve been there.
On Reddit, one guy wrote:
“I can watch porn and jerk off just fine. But with my girlfriend, I get hard at first and then lose it as soon as I try to put it in. She thinks I’m not attracted to her, but that’s not it at all. My head is racing, and I just shut down.”
Another described the mental loop that kills the moment:
“The first time it happened, I panicked. Now every time we start fooling around, I’m already thinking about losing it. And of course, I do. It’s like my dick is allergic to pressure.”
On Quora, a 27-year-old shared:
“With casual hookups, I stay hard no problem. But with my girlfriend, who I actually love, I go soft half the time. I think it’s because I care too much about what she thinks. I want to be perfect, and it ruins it.”
And one of the most common lines I hear in therapy:
“I can get hard alone, I can cum alone, I can even get hard when we’re making out. But the moment penetration is about to happen, I lose it. It’s like my body pulls the plug.”
If you’ve said something like this in your head, you’re not broken. You’re describing situational erectile dysfunction exactly the way thousands of men do online every day.
For most men, the hardest part isn’t losing the erection. It’s what happens in your head afterwards.
When situational ED hits, you might tell yourself:
That’s the real damage. Not the soft dick, but the spiral of shame and doubt that follows.
One guy on Reddit wrote:
“The second I went soft, I just wanted to disappear. She said it was okay, but I couldn’t look her in the eyes. I felt like less of a man.”
Another said:
“It’s not just about sex. It’s about confidence. I started avoiding dates, avoiding intimacy, because I was so scared it would happen again.”
This is what shame does: it isolates you. It convinces you you’re the only one, when in reality millions of men go through this exact thing. In fact, research shows ED is strongly linked with loss of self-esteem, anxiety, and depression. It’s not just in your pants, it affects your whole sense of self.
But here’s what I tell my clients: erections are not a measure of manhood. Situational ED isn’t proof you’re broken. It’s a signal that your mind and body need to reconnect, not a life sentence.
Situational ED feels like quicksand. The more you fight it, the deeper you sink. But it is possible to reset. Not overnight, not with a magic pill, but with a clear plan that works for both your body and your mind.
Your biggest enemy isn’t your penis, it’s the panic in your head.
Porn conditions you to expect instant erections and endless novelty. Real sex is slower, more intimate, and, if you’ve been stuck in a porn loop, it takes retraining.
Your erection is a reflection of your whole system.
ED meds (Viagra, Cialis) can help, not as a permanent crutch, but as a bridge. They lower the pressure and let your brain relearn that sex can succeed. Combine them with therapy or lifestyle changes for best results.
Online therapy and sex therapy are game-changers for situational ED. Talking to a professional who’s heard this story hundreds of times takes the shame out of it. And the earlier you get support, the faster the cycle breaks.
The key takeaway? Situational ED isn’t permanent. The more you face it head-on, instead of hiding it, the faster it shifts.
Situational erectile dysfunction feels humiliating, but it shouldn’t. Losing an erection during sex doesn’t mean you’re weak, unmanly, or broken. It means your brain and body aren’t syncing in that moment and that can be retrained.
In fact, research shows that millions of young men deal with ED. Most don’t talk about it. They carry it alone, pretending everything’s fine, while secretly panicking that they’ll never have normal sex again. But silence only makes it worse.
The truth? You’re not the only one. You’re not broken. And this is not forever.
Right now, sex might feel like a minefield, one wrong move and your erection disappears. That doesn’t mean this is your future. Situational ED is one of the most treatable sexual problems men face.
With the right mix of reducing porn, calming anxiety, fixing tiredness, and rebuilding partnered arousal, your body can and does bounce back. I’ve seen men go from years of panic-driven sex to confident, enjoyable penetration in a matter of months once they stopped hiding and started working on it.
If you’re stuck in the cycle, you don’t have to figure it out alone. Online therapy, sex therapy, and telehealth ED support exist because so many men go through exactly this. Taking that step isn’t weakness; it’s the start of getting your sex life back.
This is called situational erectile dysfunction. Erections work during masturbation or porn but fail with penetration because of performance anxiety, stress, porn-conditioning, or relationship pressure.
Losing erections during penetration often comes from performance anxiety, porn-induced desensitization, or stress carried into the bedroom. The more you worry about staying hard, the more your erection disappears.
Yes. Studies show that over 20% of young men report erectile dysfunction linked to problematic porn use. Excessive novelty trains the brain to prefer screens over real sex, making erections with partners harder to maintain.
Yes. Stress and exhaustion disrupt hormones, lower testosterone, and block sexual arousal. Many men report losing erections on nights they are mentally drained or physically tired.
Situational erectile dysfunction is reversible. With reduced porn use, better sleep, stress management, and therapy, most men recover normal erections with partners.
ED medications like Viagra can help temporarily, but they don’t fix the root causes. They work best when combined with therapy, anxiety reduction, and lifestyle changes.
