The penis becomes flaccid during intercourse – and it can feel both frustrating and worrying; self-esteem shrinks; you’re not alone. With me, we find the reason why it’s happening. No guesses and no standard solutions, but a targeted examination where I go through everything that affects your erection. Once the cause is clear, we create a specific treatment plan to give you back your erection. We typically work with lifestyle changes, shockwave, which improves blood flow and strengthens the tissue in the penis, and EMTT, which supports nerve function and brings back hardness.
In this article, you’ll get an overview of the most common causes – from blood vessels and nerves to psyche and lifestyle – and learn what you can do and how I can help you find the specific cause and solution for your particular problem. The goal is to restore a stable and natural erection – also during intercourse. If your penis becomes flaccid, it’s a signal from your body. And in most cases, it can be treated when we target the cause. Enjoy reading, all the good stuff is at the bottom of the page 🍆
International speaker & expert in shockwave and EMTT treatment for erectile dysfunction, peyronies & CPPPS.
When the penis becomes flaccid during intercourse, it affects more than just your sex life. It affects confidence, intimacy and desire. I meet men every week who struggle to maintain an erection or lose it mid-act. It can be intermittent, situational or a problem that has developed over months or years. Wherever you are, I can address it with you – calmly, professionally and without shame.
I offer a safe, professional and solution-oriented approach. With advanced ultrasound, targeted treatment and a focus on your body, nerves and psyche, I help you return to a stable and satisfying sex life – without unnecessary detours. My goal is for you to trust your body again, find peace in the situation and feel the joy of intimacy.
An erection depends on blood being able to flow freely into the cavernous bodies and stay there. When you lose your erection during sex, it’s often due to:
Men with incipient cardiovascular disease may experience erectile dysfunction before other symptoms appear. That’s why I always take my circulation seriously. A simple rule of thumb: mornings, masturbation and erection during foreplay can be better than erection during penetration if the venous system relaxes too quickly. This helps me to target your treatment.
The nervous system controls erection. Irritation or impingement of the pudendal nerve, pelvic floor tension or chronic pelvic pain (CPPS) can make it difficult to get and maintain an erection. Many also describe tingling, burning, discomfort in the perineum or pain during ejaculation. When pain and tension activate the body’s “alarm”, erection typically decreases during intercourse.
Signs of nerve and muscle interference can be unintentional tension in the buttocks, abdomen or pelvic floor, sitting a lot during the day, or cycling making symptoms worse. “Pulling yourself together” rarely helps here – instead, I work to silence the alarm, loosen the tissue and retrain the natural erection reflex.
Performance pressures, worries, conflicts, porn habits, stress and sleep deprivation can derail the erection reflex. Many people function well during masturbation but lose their erection during intercourse – this is a strong sign that the nervous system is in “watch mode” and that comfort, pace and focus need to be adjusted. I help you with concrete strategies so that the body can once again take control – without the brain overriding with control and criticism.
Alcohol, a very large meal, fatigue, recent illness or extended periods without sex can cause a flaccid penis during intercourse. It’s normal sometimes – the problem is when it becomes a pattern. I’ll help you distinguish between one-off incidents and persistent causes.
Seek emergency help if you experience:
Otherwise, it applies: The sooner I determine the cause, the better I can help.
I start with a calm, respectful conversation. I ask about the pattern: Does erection work in the morning? Is there a difference between masturbation and intercourse? Do you lose your erection when changing positions? Do you have pain, sensory disturbances or problems ejaculating? I use validated tools like the IIEF/SHIM to grade the problem and follow the development over time. Feel free to bring your partner if it feels right – it can provide valuable insight and peace of mind.
I assess the level of pelvic floor tension, coordination and endurance. An overactive pelvic floor can explain erectile dysfunction, premature ejaculation and pain. You’ll get a concrete explanation of what I see – and what it means for your erection. At the same time, I examine the hips, lower back and nerve pathways that can affect the signals to the penis.
With high-resolution ultrasound, I assess tissue, vessels and any plaques (Peyronie’s). I can also assess the blood flow in the penis to see if this is the problem. It’s painless and gives a clear picture of what I need to treat. Where appropriate, I will take before/after measurements so you can see your progress in black and white.
I test the course of the pudendal nerve and look for trigger points and sensitive structures in the pelvis that can “short-circuit” the erection reflex. If necessary, I use neuromodulation tests to assess nervous system activity and map out which positions and movements provoke – and which ones relieve.
If indicated, I will collaborate on blood tests (testosterone, metabolism, long-term blood sugar, lipids). I make a plan in collaboration with your own doctor/urotherapist so that you get a holistic assessment.
There is no one solution for everyone. I combine proven methods to give you both fast symptom relief and long-term recovery.
I’ll advise you on the benefits, risks and practical use – and how medication best interacts with other treatments. Never stop prescribed medication without consulting your doctor.
Short, controlled acoustic pulses stimulate microcirculation, tissue repair and new blood vessel formation in the penile shaft. In men with vascular erectile dysfunction, shockwave can improve erection quality and response to PDE5 inhibitors. The treatment is quick, without anesthesia and with minimal discomfort. A course is typically 6-8 sessions and I often supplement with targeted home exercises to enhance the effect.
EMTT uses high-energy magnetic fields to affect cellular healing processes and nerve signaling. I use EMTT specifically for pelvic pain, nerve irritation and muscular tension that can cause the penis to become flaccid during intercourse. The therapy is non-invasive and most people find it comfortable and relaxing.
With gentle, controlled stimulation, I help the nervous system “get back on track” to reduce pain and muscle tension and improve parasympathetic calm (which promotes erection). This can be crucial for CPPS and pudendal pain and can be combined with breathing and awareness techniques that you take home with you.
It’s not just a question of “squeezing”. Many people actually need to learn to let go. I instruct you in individual exercises for coordination, timing and breathing so that the pelvic floor supports – not inhibits – erection. You’ll get simple at-home exercises that can be discreetly integrated into everyday life and specific cues to use during sex so your body works with you.
I work in a down-to-earth way:
When needed, I include sexological tools and referrals for complex couple or trauma issues.
Small, consistent changes can be the difference between an erection that fades and an erection that lasts.
Age increases the risk of circulatory changes, but it’s not a judgment. Many 50-60+ men get a solid and lasting erection again with targeted efforts.
If tablets don’t work, it is often due to dose/timing, venous leakage, nerve interference or psychological overactivation. The solution may be combinations: e.g. shockwave, pelvic floor, neuromodulation and behavioral strategies. Alternatively, injection therapy or assistive devices may be relevant.
Prolonged and hard cycling can irritate the pudendal nerve. Proper saddle fit, posture variations and customized training reduce the risk. For persistent symptoms, targeted treatment can help.
Some feel the effect after 3-4 sessions, but typically I see full effect 4-12 weeks after completing the program. The results depend on the starting point and other measures.
Yes – and it’s often part of the “training”. I help you adapt pace and technique to your situation.
Never stop yourself. Talk to me and your doctor. Often there are alternatives or adjustments.
Yes, you can. I combine ultrasound diagnostics, focused shockwave, EMTT, tissue care and exercises. I can often reduce pain and improve function, and in some cases reduce the impact of curvature on sex life.
Discretion is a matter of course. You get appointments that fit your schedule, and courses are planned efficiently. I have clients from all over Denmark – especially Copenhagen and Zealand.
If your penis becomes flaccid during intercourse, it’s not a sign of weakness – it’s a signal. With the right assessment and a targeted plan, you can get your erection and calm back. I meet you without prejudice, with professional weight and a clear focus on solutions that work in your reality.

Are you unsure about what’s causing your symptoms, or whether a specialized treatment program at our clinic in Copenhagen would be right for you? If so, you can start with a brief, confidential consultation. During this consultation, we’ll assess whether your symptoms align with the areas I specialize in at MS Insight and determine what the next appropriate step might be.
The clarifying conversation is not a full consultation, diagnosis or treatment plan. It’s for those who want a serious assessment of whether it makes sense to proceed with a more thorough examination, ultrasound scan and individual plan.
The clinic is a private clinic offering an alternative treatment setup to the public system with shockwave, EMTT and NESA X for sexual dysfunctions and especially erectile dysfunction, peyronies and pelvic pain.
