What causes a short pain in the penis during an erection?
Patient's Query
Hello doctor,
This morning, I stretched myself while I had an erection and squeezed my thighs together. I felt a short pain in the penis while doing that. I was wondering if this kind of movement could be dangerous for the penis or not at all.
Kindly help.
Thank you.
Hello,
Welcome to icliniq.com.
I understand your concern.
From what you have described, stretching while having an erection and squeezing your thighs together, followed by a brief pain, this kind of movement is not usually dangerous as long as the pain lasts only a few seconds or minutes. There was no popping or snapping sound, you did not lose your erection right away, and there was no bruising, swelling, or bending of the penis. You are still able to urinate normally, and your erections after that are not painful or unusually curved.
This may have been a mild strain of the ligaments or connective tissue in the penis, or a short compression of the erectile tissue, mainly due to the thighs pressing inward. When the penis is erect, it becomes filled with blood and less flexible, so sudden pressure or bending can cause discomfort.
You should see a doctor if you notice any of the following:
-
Ongoing or increasing pain.
-
Bruising or skin discoloration.
-
Swelling.
-
A change in shape.
-
Blood in your urine or coming from the urethra.
These symptoms could mean something more serious, such as a penile fracture, which is rare but needs urgent treatment.
If your pain was brief and there are no other symptoms, it is probably nothing serious. Just be careful not to put pressure or strain on your erect penis in unusual positions.

Hello doctor,
Thank you for your bright and complete answer.
Hello,
Welcome back to icliniq.com.
I understand your concern.
Taking occasional short-term vitamin E after minor pain is not harmful and may provide some antioxidant benefit.

Patient's Query
Hello doctor,
Thank you for your prompt response.
-
Is this dosage enough to prevent complications?
-
I am a little anxious about it, so I would like to know when it is wise to take it, like when there is pain or even if there is not.
-
For example, sometimes the penis may bend during penetration when it is not fully erect. Could this be harmful, or is it only a concern if there is pain?
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
1. Is 150 to 300 mg of vitamin E enough to prevent complications? That dose (about 200 to 400 IU (international units)) is within the commonly used range in studies, especially for conditions like early Peyronie's disease.
But here is the key point: Vitamin E is not a magic shield. It may support healing but will not prevent injury or fibrosis alone. It is more of a supplement to recovery than a guaranteed protector. That dose is fine if you use it occasionally for peace of mind. But taking it routinely without a medical reason, especially for long periods, is not necessary, and in high doses over time, it could slightly increase bleeding risks.
2. When should you consider taking vitamin E? You might consider short-term use (a week or two) only if:
-
There was a painful bend or trauma during sex or masturbation
-
You feel a lingering ache afterwards.
-
You are worried about micro-injury and want to support tissue recovery.
But you do not need to take vitamin E preventively if there is no pain, bruising, swelling, or dysfunction. It is not a vaccine for penile trauma. It is more of a mild supportive tool after an apparent injury.
3. Can the penis bending during sex cause harm, even without pain? During sex, especially if the penis is not fully hard (semi-erect), it is more flexible but also more prone to accidental bending or buckling. Minor bending without pain is usually harmless. A painful and sudden bend, especially with a popping sound or swelling, is the one to watch for, and that can mean actual trauma such as a penile fracture or microtears in the tunica albuginea.
In short:
-
If the penis bends slightly and there is no pain, it is not dangerous, and there is no need for vitamin E.
-
If there is a mild ache after sex, it is usually safe, and you may use vitamin E for a short time if you wish.
-
If a painful bend with bruising or swelling occurs, seek medical attention. After a doctor's evaluation, vitamin E may be used as part of the care.
You care about your health, which is excellent. Most minor incidents during sex or stretching do not cause long-term issues. The penis is surprisingly resilient; as long as you listen to your body and avoid painful, forceful movements, you are unlikely to suffer damage. If your anxiety continues, we can discuss ways to reduce the fear of injury so it does not become a barrier to a healthy sex life.
I hope I have answered your question.

Patient's Query
Hello doctor,
Thank you for your prompt response.
Indeed, I was anxious about it for the last weeks. I went through a breakup and new encounters, so I wanted to do well, with a bit of fear of performance. During my last intercourse, I was a bit nervous, and my erection was not perfect, so I helped myself with my hand to make it and applied force on my penis during the first minutes. No pain and no extreme bending, but then I was worried about it and took vitamin E. After this, my erections were firm and perfect. So I am more confident now. This was eight days ago.
Should I continue vitamin E, or is it useless at this point?
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
Based on what you described, there was no pain, no trauma, and your erections since then have been intense and regular. You took vitamin E as a precaution, and now it has been eight days with no symptoms.
In this case, you do not need to continue taking vitamin E further. You have already supported your body through the sensitive period, and no ongoing issue requires antioxidant or anti-inflammatory support.
What to do now?
-
You can safely stop vitamin E.
-
Focus on restful sleep.
-
Eat a healthy diet rich in zinc, omega-3s, and leafy greens, which naturally support blood flow and tissue health.
-
Manage stress, especially around performance, and pay attention to how your body feels rather than what it “should” do.
It is very common after a breakup or in a new relationship to feel pressure to perform sexually. This pressure can backfire, creating a cycle of stress, softer erections, and more stress. The fact that your erection returned strongly after the encounter is a clear sign your body is functioning well; it just needs some mental space to relax.
Confidence returns with positive, low-pressure sexual experiences, open communication if you are with a partner, and even moments of laughter or lightness during intimacy.
You did everything right; you listened to your body, acted early, supported your recovery, and asked thoughtful questions.
I hope I have answered your question.

Patient's Query
Hello doctor,
Thank you for your prompt response.
My doctor recommended that I try Tadalafil 5 mg when anxious or tired and take one pill on demand. I did this last week, and it was a good experience. I just have three questions:
-
The morning after taking it, while sleeping, I had such a powerful erection that I had to stand up to make it pass because it was a little painful. Is this concerning?
-
After having a few intercourses and orgasms the same night, I can feel soreness and pain around and on the penis when I want to start again. No trauma was involved. Is this normal?
-
Is it a good idea and safe to take it occasionally at this level?
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
After eight days, should you continue vitamin E?
In your case:
-
You had no pain, significant bend, bruising, or swelling.
-
Erections returned to normal and strong after that encounter.
-
It has been eight days without symptoms.
You do not need to continue Vitamin E now. It has likely provided whatever minor support it could in the early few days; beyond that, it does not add any significant healing effect if there is no actual injury or inflammation.
When to stop: You can stop right now; no tapering is needed. There is no proven benefit to taking it “just in case” once you are symptom-free.
A few quick reminders for you:
-
Mild manipulation of the penis when not fully erect (such as with your hand during early intercourse) is not harmful unless you feel pain or force a sharp bend.
-
Your improved erection after reassurance shows a strong mind-body link; your confidence and calmness are already helping.
-
Vitamin E applies after a mild injury (aches, soreness, or trauma) but not as a daily protective pill; think of it like ice after a strain, not a vitamin for strength.
Emotional angle: You mentioned a breakup, new encounters, and performance anxiety, which are very real and very common. These emotional factors can:
-
Causes temporary erectile softness.
-
Make you hyper-aware of every sensation.
-
Increase anxiety around doing “everything right.”
But here is what is essential:
-
You listened to your body.
-
You avoided panic despite worry.
-
Your function came back strong; you are healthy.
Stop Vitamin E now. It has served its short-term purpose. No harm has been done, and there is no ongoing need. Stay confident. You are doing great, both physically and emotionally. If anxiety ever creeps back in, feel free to talk it through; I am here.
I hope I have answered your question.

Patient's Query
Hello doctor,
Thank you for your prompt response.
I am fully aware of the use of vitamin E. And for this use of Tadalafil 5 mg on demand, what is your point of view?
Is it a good thing to do for a short time?
And what about the side effects that I have been experiencing, as mentioned before: the morning after taking it, while sleeping, I had such a powerful erection that I had to stand up to make it pass, because it was hurting a little. Is it concerning?
After having a few intercourses and orgasms the same night, I can feel soreness and pain around and on the penis when I want to start again. No trauma was involved. Is it normal?
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
Tadalafil 5 mg on demand. Is it okay? Yes, using Tadalafil 5 mg on demand (instead of daily) is perfectly acceptable and even preferred in some cases, especially for younger men or those who do not need support daily. Use it about one to two hours before intercourse. It remains active for 36 hours (nicknamed the “weekend pill”). It can be taken as needed, but not more than once daily. Short-term use, like you are doing, is reasonable if:
-
You want to boost confidence or break a performance anxiety cycle.
-
Your doctor has not found a cardiovascular contraindication.
Side effects you are describing. Are they concerning? Let us go one by one:
Powerful nighttime erection that was slightly painful and forced me to stand up to relieve it. This sounds like prolonged nocturnal tumescence, possibly enhanced by the long half-life of Tadalafil. It is not necessarily dangerous unless:
-
The erection lasts more than four hours continuously (which would suggest priapism, a medical emergency).
-
You regularly wake up with painful, hard erections that do not go down with simple measures like walking. Since your erection subsided quickly and was not constant or lasting more than four hours, it is more likely a benign exaggerated physiological response. Standing up to relieve it is acceptable and common.
Soreness or pain around or on the penis after multiple intercourses and orgasms in one night. This is also very normal, especially if:
-
There were multiple rounds of sexual activity with minimal recovery time.
-
Lubrication was suboptimal, leading to friction-based irritation.
-
There is some engorgement fatigue; the penis is a vascular organ, and repetitive strain, like any muscle or tissue, can cause soreness. Mild pain or soreness after multiple ejaculations without trauma is common and usually not a sign of injury.
Summary of my view
-
Tadalafil 5 mg on demand is effective and safe for short-term or occasional use, making it a good strategy for your case.
-
Morning after hard erection: Common; not concerning unless painful and lasting more than 4 hours (priapism).
-
Soreness after multiple acts: Normal; the penis needs rest like any tissue. Watch for signs of trauma.

Patient's Query
Hello doctor,
Thank you for your prompt response.
Indeed, I had a rough breakup recently and was nervous about new relationships. I take 5 mg of Tadalafil once or twice a week, depending on how I feel and what I will do. I have been doing it for three weeks, which has dramatically helped me feel comfortable.
Is it a good approach during such moments?
How long can I do it?
Is there a time limit, or should I stop once my confidence is restored?
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
Safety and duration: Low-dose use (5 mg once or twice a week) is well within the safe range for healthy individuals without contraindications (unstable heart disease, severe hypotension, etc.). Tadalafil is approved for daily use at 5 mg, so your intermittent use is even less total exposure. There is no strict medical time limit; people can use it for years when indicated, as long as their blood pressure, cardiovascular status, and kidney/liver function remain fine. Some of the side effects you should watch for are headache, flushing, nasal congestion, backache, or prolonged erections.
Psychological angle: After a breakup, performance anxiety can be amplified. Tadalafil can help break the cycle of anxiety leading to poor performance, which then leads to more anxiety. The ideal goal is to wean off once confidence is rebuilt, so you are not reliant on medication to feel sexually capable.
Based on this, the practical plan. Keep it at 5 mg once or twice a week; no need to escalate unless advised. Reassess in two to three months and try encounters without it when ready. If you still need it beyond six to nine months purely for confidence (and not a medical erectile dysfunction issue), consider addressing the anxiety side, mindfulness, gradual exposure, or a few sessions with a sex therapist, which can help.
Bottom line: You can safely keep doing what you are doing for now. It is a reasonable short-term aid during an emotionally vulnerable time, as long as your cardiovascular health is fine. The right time to stop is when you feel you can be relaxed and confident without it, not just when the box runs out.
I hope I have answered your question.

Patient's Query
Hello doctor,
Thank you for your prompt response.
I would also like to know if there is a risk of tolerance after taking it for a while, or if 5 mg will still be as effective as it is now. I am in good health and very active.
-
Is there a potential risk if I take it more than twice weekly?
-
What limit would you advise for my case in terms of mg and frequency?
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
Let me give you the answer point by point.
Risk of tolerance: No pharmacological tolerance has been documented with Tadalafil. If it feels less effective over time, the reason is usually progression of the underlying condition (such as worsening vascular function, hormonal changes, or stress), not the drug itself.
Safety for someone active and healthy: For a healthy, active man with no cardiovascular disease and normal kidney or liver function, taking 5 mg once daily is considered safe in clinical practice. Since you only take it once or twice a week, your total exposure is far below what has been proven safe in daily regimens.
Practical limits for your case: Daily limit: The maximum approved dose is 20 mg in 24 hours. The long-term limit is up to 5 mg every day for years without problem. In your case, 5 mg daily is well within safe limits, and you could take it more than twice a week without concern.
I hope I have answered your question.

Patient's Query
Hello doctor,
Thank you for your prompt response.
I would like to know if the side effects of taking four doses of 2.5 mg per week or two doses of 5 mg per week are the same.
Also, I am just worried about the effect on the eyes. Is there a chance of damage at these levels after taking it for a while?
I had an eye exam a few years ago, and the results were good. Should I worry about these side effects?
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
Tadalafil 2.5 mg once per week for four weeks versus 5 mg once per week for two weeks are pharmacologically very similar in terms of total drug exposure and, therefore, the likelihood and type of side effects. The main difference is timing:
-
5 mg once per week for two weeks: Higher peaks in concentration on the days you take it, but drug-free days in between.
-
2.5 mg once per week for four weeks: Smaller peaks spread more evenly throughout the week, so the effect is steadier, with a more constant drug in your system.
From a side-effect perspective: If you are prone to peak-related effects (such as flushing, headache, or mild nasal congestion), taking 2.5 mg more frequently might feel gentler. However, if you tolerate Tadalafil well, the difference is minimal.
Eye-related concerns: The main rare eye issues linked to PDE5 inhibitors like Tadalafil are:
-
NAION (non-arteritic anterior ischemic optic neuropathy) – Sudden painless vision loss in one eye, extremely rare, usually in people with vascular risk factors and a small optic nerve "crowded disk" anatomy.
-
Mild temporary visual changes (bluish or tinged vision, slight blur) – Much less familiar with Tadalafil than Sildenafil.
-
There is no robust evidence that long-term, low-dose Tadalafil causes progressive retinal damage in healthy eyes.
At your described doses (≤10 mg/week total), the risk is extremely low in someone with normal eye health and no primary vascular disease.
Good practice:
-
Have a baseline eye exam (you already did).
-
Repeat every one to two years.
-
Seek care immediately if you ever experience sudden vision changes.
I hope I have answered your question.
Let me know if I can assist you further.
Thank you.
Patient's Query
Hello doctor,
Thank you for your prompt response.
So, are there no significant risks at these levels, even if I take it for several weeks?
What total amount per week should I expect to be perfectly safe?
I have only taken it twice a week and have had no side effects.
Please help.
Thank you.
Hello,
Welcome back to icliniq.com.
I understand your concern.
For long-term safety, here is what I would consider a conservative upper limit:
Daily low-dose regimens for erectile dysfunction or LUTS (lower urinary tract infections) (2.5–5 mg/day) are approved for continuous use, meaning 35 mg/week is considered safe in healthy men. Since you are at 10 mg/week right now, you are far below that ceiling. Staying under 20–25 mg/week is safer for most healthy people and provides a generous safety margin.
If you are symptom-free, you could keep your current twice-a-week pattern for weeks or months without any problem. Just keep in mind:
-
Avoid combining it with nitrates
-
Monitor blood pressure
-
Pause if you notice any sudden visual or hearing changes.
I hope I have answered your question.
Let me know if I can assist you further.
Thank you.
