Genital organs


Hello doctor, a few days ago I had sexual intercourse at an adult venue.
I used a condom, but later while showering, I noticed some small red spots on the glans of my penis.
There are also some on the foreskin, but they are not very noticeable, and there is no pain or itching.
I'm worried that I might have contracted some kind of disease.

I understand your anxiety: Hello, your anxiety is something that many people, especially men, may experience.
Based on your description, I believe it could be a common bacterial or fungal infection.
Common sexually transmitted infections, such as gonorrhea, typically present with urethritis, while syphilis may show specific skin lesions.
In addition to infections, it is also important to consider allergic reactions, such as to lubricants used with condoms.
My recommendations are as follows: 1.
Temporarily apply an appropriate topical ointment.
2.
Check your urine to confirm whether there is urethritis or other issues.
3.
After 6-8 weeks, have a blood test to screen for syphilis and HIV.
4.
Remember that any encounter leaves a trace; it is best to use condoms throughout and avoid kissing or oral sex, which involve direct contact with bodily fluids.

When it comes to noticing red spots on the penis, especially after engaging in sexual activity, it's important to approach the situation with caution and awareness. While I cannot provide a definitive diagnosis, I can offer some insights into potential causes and considerations based on your description.

Firstly, the presence of red spots on the penis, particularly after a recent sexual encounter, can be attributed to several factors. One common cause could be irritation or friction from sexual activity, even when using a condom. This can lead to small abrasions or petechiae (tiny red or purple spots caused by bleeding under the skin) on the sensitive skin of the penis. If the spots are not accompanied by pain, itching, or any other symptoms, it may simply be a result of minor irritation.

Another possibility is the development of a condition known as balanitis, which is inflammation of the glans (the head of the penis). This can occur due to various reasons, including poor hygiene, allergic reactions to soaps or lotions, or infections. Balanitis can present as redness, swelling, and sometimes discharge, but it may not always be painful.

Sexually transmitted infections (STIs) are also a concern, especially after unprotected sexual encounters. Some STIs can manifest as red spots or lesions on the genital area. For example, herpes simplex virus can cause small red bumps or blisters, while human papillomavirus (HPV) can lead to warts. However, these conditions typically present with additional symptoms, such as pain, itching, or unusual discharge.

Given your situation, here are some recommendations:
1. Monitor Symptoms: Keep an eye on the red spots. If they persist, change in appearance, or if you develop additional symptoms such as pain, itching, or discharge, it would be wise to seek medical attention.

2. Practice Good Hygiene: Ensure that you maintain good genital hygiene. Gently clean the area with mild soap and water, and avoid using harsh chemicals or heavily scented products that could irritate the skin.

3. Avoid Irritation: If you suspect that friction or irritation from sexual activity is the cause, consider using a water-based lubricant during future encounters to reduce friction.

4. Consult a Healthcare Provider: If the red spots do not resolve within a few days or if you have any concerns about STIs, it is crucial to consult a healthcare provider. They can perform a physical examination and may recommend tests to rule out infections or other conditions.

5. Consider STI Testing: Given the recent sexual encounter, it may be prudent to get tested for STIs, even if you do not have symptoms. Early detection and treatment are key to managing any potential infections.

In conclusion, while red spots on the penis can be concerning, they are not always indicative of a serious condition. However, due to the potential for STIs and other medical issues, it is essential to remain vigilant and seek medical advice if necessary. Taking proactive steps in monitoring your health and maintaining open communication with healthcare professionals is vital for your overall well-being.
