Redness during masturbation?


Hello, doctor: I would like to ask why I experience widespread redness on my chest, abdomen, and arms during masturbation, which disappears after ejaculation.
What could be the cause of this?

Hello: If the symptoms are confirmed to disappear in a short time, it is a manifestation of the nervous system.
However, if they persist until the next day, please seek medical attention for an examination.

More Info


The appearance of red spots on the body during masturbation can be concerning, but it is often related to physiological responses rather than a serious medical issue. Here are some potential explanations for why you might experience these red spots:
1. Increased Blood Flow: During sexual arousal and orgasm, the body undergoes various physiological changes. One of these changes is increased blood flow to the skin, which can cause temporary redness or flushing in certain areas, such as the chest, abdomen, and arms. This is a normal response and usually resolves shortly after the activity ends.

2. Hormonal Changes: The release of hormones such as adrenaline and norepinephrine during sexual arousal can lead to changes in skin coloration. These hormones can cause blood vessels to dilate, resulting in a flushed appearance.

3. Skin Sensitivity: Some individuals may have more sensitive skin that reacts to physical stimulation, including friction during masturbation. This can lead to localized redness or irritation, which may appear as red spots. If the skin is rubbed or pressed against surfaces, it can also cause temporary redness.

4. Heat and Sweating: Engaging in sexual activity can raise your body temperature and induce sweating. This can lead to a flushed appearance and may also cause irritation if sweat accumulates on the skin.

5. Allergic Reactions: In some cases, if you are using lubricants, lotions, or other products during masturbation, you may be experiencing an allergic reaction or irritation from those substances. If the red spots persist or are accompanied by itching or discomfort, it may be worth considering whether any products you are using could be the cause.

6. Anxiety or Stress: If you feel anxious or stressed during masturbation, this can also lead to physical symptoms, including flushing or redness of the skin. The body's stress response can trigger various physiological changes, including increased heart rate and blood flow.

7. Dermatological Conditions: While less common, certain skin conditions such as hives or eczema can cause red spots to appear. If you notice that the spots are persistent, itchy, or accompanied by other symptoms, it may be advisable to consult a dermatologist for further evaluation.

In summary, the red spots you are experiencing during masturbation are likely a result of normal physiological responses, such as increased blood flow and skin sensitivity. However, if these spots are persistent, painful, or accompanied by other concerning symptoms, it would be wise to consult a healthcare professional for a thorough evaluation. They can provide personalized advice and determine if any underlying conditions need to be addressed. Remember, it's always better to seek medical advice if you have concerns about your health.
