Red Bumps on Glans: Symptoms After Unprotected Sex - Internal Medicine

Worried about sexually transmitted infections (STIs)?


I would like to ask about the situation where there are small red spots around the corona of the glans that are not painful but itchy, with no discharge.
What could this be? A few days ago, I went to a hot spring and had unprotected sexual intercourse with my girlfriend during that time.

Hello, based on your description, it seems to be "penile pearly papules." This is a normal physiological phenomenon that is not caused by bacteria or viruses; it is simply a proliferation caused by glandular secretion and irritation from smegma.
Therefore, it is not pathogenic and does not require treatment.
If the number increases significantly and starts to have an odor, then medical attention would be necessary.
Thank you for your inquiry.

More Info


The presence of red bumps on the glans, particularly after engaging in unprotected sexual intercourse, can be concerning and may indicate a variety of conditions. Given your description of the symptoms—red bumps that are itchy but not painful and the absence of any discharge—there are several potential explanations to consider.

Firstly, one possibility is that these red bumps could be a manifestation of a sexually transmitted infection (STI), such as herpes or human papillomavirus (HPV). While you mentioned that there is no discharge, some STIs can present with localized symptoms like bumps or lesions without significant discharge. It is important to note that even if you have previously tested negative for STIs, the incubation period for certain infections can vary, and new infections can occur after your last test. Therefore, it may be prudent to consider retesting for STIs, especially if you have engaged in unprotected sex.

Another potential cause for the red bumps could be a dermatological condition, such as folliculitis, which is an inflammation of the hair follicles that can occur due to irritation or infection. This condition can sometimes arise after activities like hot tub use, where bacteria can thrive in warm, moist environments. Folliculitis typically presents as small red bumps that may be itchy but are not usually painful.

Additionally, contact dermatitis is another possibility. This condition can occur when the skin reacts to irritants or allergens, which could include soaps, lotions, or even the materials in condoms or lubricants if they were used in previous encounters. The skin in the genital area is sensitive, and reactions can manifest as red, itchy bumps.

Given that you have also mentioned that the bumps are located around the corona of the glans, it is essential to consider the possibility of balanitis, which is inflammation of the glans. This condition can be caused by infections, poor hygiene, or irritants and can lead to redness, swelling, and itching.

In terms of management, it is advisable to avoid further irritation to the area, such as avoiding tight clothing or irritants like scented soaps. Over-the-counter hydrocortisone cream may help alleviate itching and inflammation, but it is crucial to consult with a healthcare provider for a proper diagnosis and treatment plan. A dermatologist or urologist can perform a physical examination and may recommend tests such as swabs or cultures to identify any underlying infections.

In conclusion, while the symptoms you are experiencing could be attributed to various causes, including STIs, dermatological conditions, or irritant reactions, it is essential to seek medical evaluation to determine the exact cause. Early diagnosis and treatment are crucial in managing any potential infections and preventing complications. Always prioritize safe sex practices to reduce the risk of STIs and other complications in the future.
