Red Spots During Masturbation: Is It Syphilis or Skin Allergy? - Urology

Erythema during masturbation?


When I masturbate, my body gets warm and I develop patchy red spots on my abdomen and chest, but they disappear after I finish.
I have previously been treated for syphilis, and my levels have decreased by four times, indicating effective treatment.
Could this be related to syphilis, or is it a skin allergy? Can you help me understand? This has been bothering me for some time.

Hello: It is not due to syphilis, but your syphilis still requires long-term monitoring and should not be taken lightly, as some individuals may still experience an increase in titers during the follow-up period.

More Info


When experiencing red spots on the abdomen and chest during masturbation, it is understandable to be concerned about potential underlying conditions, particularly if there is a history of syphilis. However, based on the symptoms you describe, it is more likely that these red spots are related to a skin reaction rather than a sexually transmitted infection like syphilis.

The transient nature of the red spots—appearing during masturbation and disappearing afterward—suggests that they may be a form of skin allergy or irritation rather than a persistent infection. This could be due to several factors, including increased blood flow and body temperature during physical arousal, which can lead to temporary flushing or redness of the skin. This phenomenon is often referred to as "exercise-induced urticaria" or "heat rash," where the skin reacts to increased temperature or physical exertion.

In addition to the physiological response, consider other potential causes for your symptoms:
1. Allergic Reactions: If you have recently changed soaps, lotions, or laundry detergents, these could be irritating your skin. Allergic reactions can manifest as red, itchy spots, especially in sensitive areas.

2. Chafing or Friction: Physical activity, including masturbation, can cause friction against the skin, leading to irritation and redness. This is particularly common if the skin is not adequately lubricated.

3. Heat Rash: Increased sweating and heat during masturbation can lead to blocked sweat glands, resulting in a heat rash characterized by red bumps or spots.

4. Psychological Factors: Anxiety or stress related to sexual activity can also cause physical symptoms, including skin reactions. The body's stress response can lead to flushing or hives in some individuals.

Regarding your concern about syphilis, it is important to note that syphilis typically presents with specific symptoms, including sores, rashes, and systemic signs that do not resolve quickly. If you have undergone treatment for syphilis and your symptoms have improved, it is less likely that the red spots are related to this infection. However, if you have any doubts or if the symptoms persist, it is crucial to consult a healthcare professional for a thorough evaluation.

In summary, while your symptoms could be concerning, they are more likely related to skin irritation or an allergic reaction rather than a sexually transmitted infection. It is advisable to monitor your symptoms and consider factors such as skin care products, hygiene practices, and any recent changes in your routine. If the red spots continue to appear or worsen, or if you experience additional symptoms, seeking medical advice is essential to rule out any serious conditions and to receive appropriate treatment.

Hello, based on your situation, it is likely not a sexually transmitted infection, but rather a possible fungal infection. If it resolves on its own, it may be related to blood circulation. However, if it persists or increases, it is advisable to consult a urologist.
