Penile pain has a wide range of causes, from minor skin irritation that resolves on its own to infections and structural problems that need treatment. The most common culprits are friction or contact irritation, infections of the urethra or foreskin, and inflammation related to the prostate or pelvic floor. What’s causing your pain usually depends on where exactly it hurts, when the pain started, and whether you have other symptoms like discharge, swelling, or changes in skin appearance.
Friction, Irritation, and Skin Reactions
The simplest explanation is often the right one. Friction from sexual activity, rough clothing, or vigorous exercise can leave the skin of the penis raw, sore, or tender. This kind of pain is usually on the surface, feels like a burn or chafe, and improves within a day or two with rest.
Contact irritation is another frequent cause. Soaps, shower gels, latex condoms, and scented detergents can trigger a reaction on sensitive penile skin. The result is redness, itching, mild swelling, or a stinging sensation. Switching to a soap-free wash and trying hypoallergenic condoms designed for sensitive skin often clears this up. If the irritation keeps coming back despite removing obvious triggers, a skin condition like lichen sclerosus may be involved. This causes white, slightly raised patches on the foreskin or glans that look like thin, wrinkly parchment. Over time it can lead to scarring that makes urination or sex painful.
Infections That Cause Burning or Discharge
Pain during urination, especially paired with discharge from the tip of the penis, points toward urethritis, an inflammation of the tube that carries urine out of the body. The most common infectious causes are chlamydia, gonorrhea, and a lesser-known organism called Mycoplasma genitalium. Discharge can range from clear and watery to thick and yellow-green. Some men also notice itching at the opening of the penis. Not all urethritis produces obvious discharge, though. Some infections cause only a mild burning with urination that’s easy to dismiss.
Genital herpes is another possibility, particularly if the pain is accompanied by small blisters or open sores on the shaft, foreskin, or glans. Herpes outbreaks can also cause inflammation at the urethral opening, making urination painful even without visible sores in that area. Syphilis, by contrast, typically starts as a single painless sore, but secondary stages can involve broader discomfort.
A bladder or urinary tract infection can produce a deep, aching pain in the penis along with frequent, urgent urination and a burning sensation. These infections are less common in younger men but become more likely with age or after catheter use.
Balanitis: Infection Under the Foreskin
Balanitis is inflammation of the head of the penis, and it’s especially common in uncircumcised men. It causes redness, swelling, soreness, and sometimes a thick discharge under the foreskin. The most frequent cause is a yeast overgrowth, particularly in men with diabetes, which is the most common underlying condition linked to balanitis. Bacterial infections can also be responsible.
Poor hygiene plays a role, but so does over-washing with harsh soaps, which strips away protective bacteria and creates an environment where irritation and infection thrive. If the foreskin becomes too tight or swollen to retract, that’s a sign the inflammation has progressed and needs medical attention.
Peyronie’s Disease and Scar Tissue
If your pain is most noticeable during erections and you’ve started noticing a curve or bend in your penis that wasn’t there before, Peyronie’s disease is a likely explanation. This condition develops when small, repeated injuries to the penis (often from normal sexual activity) trigger an abnormal healing response. Instead of repairing normally, the body lays down dense, fibrous scar tissue called plaque inside the shaft.
Pain tends to be worst in the early, active phase of the disease, when inflammation and swelling are irritating nerve endings in the affected area. This phase can last anywhere from several months to over a year. Many men find that the pain gradually fades as the plaque stabilizes, but the curvature may remain or worsen. The condition affects roughly 1 in 10 men at some point, though many cases go unreported.
Pelvic Pain That Shows Up in the Penis
Pain in the penis doesn’t always originate there. Chronic prostatitis, also called chronic pelvic pain syndrome, can cause aching or discomfort in the penis, scrotum, perineum (the area between the scrotum and anus), lower abdomen, and lower back. The hallmark is pain lasting three months or more that may shift between these areas or affect several at once.
This type of pain often worsens during or after urination, ejaculation, or prolonged sitting. The exact cause is poorly understood. It may involve nerve damage in the pelvic area, an immune system response to a past infection, or chronic tension in the pelvic floor muscles. It’s not a bacterial infection in most cases, which is why antibiotics frequently don’t help. Treatment usually focuses on pelvic floor physical therapy, stress management, and addressing the specific pattern of symptoms.
Penile Fracture
A penile fracture is a rupture of the tough tissue that surrounds the erectile chambers. It happens during vigorous sexual activity or, less commonly, from forceful bending of an erect penis. There’s no mistaking it: you’ll hear a popping or cracking sound, lose your erection immediately, and experience severe pain. The penis rapidly swells and turns purple or black from blood pooling under the skin.
This is a surgical emergency. Without prompt repair, a penile fracture can cause permanent curvature, erectile dysfunction, or both. If this description matches what you experienced, go to an emergency room.
Priapism: An Erection That Won’t Stop
An erection lasting more than four hours that isn’t related to sexual arousal is called priapism, and it’s a medical emergency. The more dangerous form, ischemic priapism, happens when blood gets trapped in the erectile tissue and can’t drain. The shaft feels completely rigid while the tip stays soft, and the pain progressively worsens. After about four hours without fresh blood flow, the oxygen-starved tissue starts to suffer permanent damage.
Nonischemic priapism, caused by abnormal arterial blood flow (often after an injury), is less urgent. The penis is erect but not fully rigid, and it’s usually not painful. Both types require medical evaluation, but ischemic priapism needs emergency treatment to prevent lasting harm. Sickle cell disease, certain medications, and recreational drugs are common triggers.
When the Pain Needs Urgent Attention
Most penile pain from friction or mild irritation resolves within a few days. Some situations call for prompt action:
- An erection lasting more than four hours that isn’t related to arousal. Go to an emergency room immediately.
- A popping sound during sex followed by rapid swelling and bruising. This suggests a fracture and needs emergency surgery.
- Discharge from the urethra with or without burning. This likely indicates an infection that can be diagnosed with a simple test and treated.
- Pain lasting more than four hours with no clear cause, or pain accompanied by unexplained symptoms like fever, swelling, or skin changes.
- White patches, persistent sores, or lumps that don’t heal within two weeks.
For pain that’s mild, came on gradually, and doesn’t involve any of the above, starting with your primary care doctor or a urologist is the right move. Many causes of penile pain are straightforward to diagnose and treat once you describe the timing, location, and any accompanying symptoms.
