Bumps Near the Base of the Penis: Possible Causes and Concerns - Urology

More Info

---

When it comes to bumps near the base of the penis, particularly after a sexual encounter, it is essential to approach the situation with caution and awareness of potential sexually transmitted infections (STIs) or other dermatological conditions. Based on your description, several possibilities could explain the bump you are experiencing.

Firstly, it is important to consider the nature of the bump. You mentioned that it resembles a pimple or mosquito bite, is hard to the touch, and has a central point that feels like a wound but is not painful or itchy. These characteristics could suggest a few different conditions:
1. Folliculitis: This is an inflammation of the hair follicles, often caused by bacterial infection, irritation, or blockage. It can present as small red bumps that may resemble pimples. If the bump is not painful and does not show signs of infection (such as increased redness, swelling, or pus), it may resolve on its own.

2. Pearly Penile Papules: These are small, harmless bumps that can appear around the corona of the glans penis. They are normal anatomical variations and are not associated with any disease or infection.

3. Genital Warts: Caused by the human papillomavirus (HPV), genital warts can appear as small, flesh-colored or gray bumps. They may not be painful or itchy initially, but they can grow in size or number over time. If the bump changes in appearance or begins to itch or hurt, it would be wise to seek medical evaluation.

4. Herpes Simplex Virus (HSV): While you mentioned that the bump is not painful, herpes lesions typically present as painful blisters or sores. However, some individuals may experience atypical presentations. If you develop additional symptoms, such as flu-like symptoms or more lesions, it would be important to get tested.

5. Other Dermatoses: Conditions such as sebaceous cysts or other benign skin lesions can also present as bumps in the genital area. These are usually harmless and may not require treatment unless they become bothersome.

Given that you had unprotected oral sex, it is prudent to consider the possibility of STIs. While the bump may not currently exhibit classic signs of an STI, it is essential to monitor it closely. If it persists, changes in appearance, or if you develop any new symptoms (such as pain, itching, or discharge), you should seek medical attention.

In terms of next steps, I recommend the following:
- Self-Monitoring: Keep an eye on the bump for any changes in size, color, or sensation. If it resolves on its own, that is a positive sign.

- Consult a Healthcare Provider: If the bump does not improve or if you have any concerns about STIs, it is advisable to see a healthcare provider. They can perform a physical examination and may recommend testing for STIs, including HPV, herpes, and other infections.

- Practice Safe Sex: Moving forward, consider using protection during oral and penetrative sex to reduce the risk of STIs.

In conclusion, while the bump you described may not immediately suggest a serious condition, it is essential to remain vigilant and proactive about your sexual health. Regular check-ups and open communication with healthcare providers can help ensure any potential issues are addressed promptly.
