Confirm whether it is a sexually transmitted infection (STI)?


Hello doctor, I have noticed a red spot on my penis that resembles a papule.
I have a fixed sexual partner of the opposite sex, and we have been together for six months, always using condoms except for oral sex.
My partner had a Candida infection about a month ago, but there have been no recurrences since then.
Given the current situation, could this be a sexually transmitted infection, or is it just a regular bacterial infection?

Ah Xiong: Hello, it is possible that you have an infection, but whether it is a sexually transmitted infection (STI) needs to be confirmed through testing.
Generally, the likelihood of a bacterial or fungal infection is higher.
If you have any further questions, feel free to ask again so we can discuss and research together.
Information from the internet should only be used as a reference; if necessary, you should seek medical attention at a healthcare facility.

When it comes to concerns about sexually transmitted infections (STIs) and urological health, it is essential to approach the situation with a clear understanding of the symptoms, potential risks, and the importance of medical evaluation. Based on your description, you have noticed a red bump on your penis that resembles a papule. You have a stable sexual relationship with a partner, and you both consistently use condoms, except for oral sex. Your partner had a yeast infection (likely caused by Candida) a month ago, which has since resolved without recurrence.

Firstly, it is important to note that while using condoms significantly reduces the risk of transmitting STIs, it does not eliminate the risk entirely, especially in the case of oral sex. Certain infections, such as herpes simplex virus (HSV) and human papillomavirus (HPV), can still be transmitted through oral-genital contact. The appearance of a red bump could be indicative of several conditions, ranging from benign to more concerning.

1. Possible Causes of the Red Bump:
- Folliculitis: This is an inflammation of the hair follicles, which can present as small red bumps and is often caused by bacterial infection or irritation.

- Pearly Penile Papules: These are small, harmless bumps that can appear around the corona of the glans and are normal anatomical variations.

- Genital Warts: Caused by certain strains of HPV, these can appear as small, flesh-colored or red bumps.

- Herpes: If the bump is painful or accompanied by other symptoms like itching or burning, it could be a sign of a herpes outbreak.

- Yeast Infection: Given your partner's recent history, a yeast infection could also cause irritation or bumps on the penis.

2. Importance of Medical Evaluation:
- Given the uncertainty regarding the nature of the bump, it is crucial to consult a healthcare professional for an accurate diagnosis. A urologist or dermatologist can perform a physical examination and may recommend tests, such as swabs or biopsies, to determine the cause of the bump.

- If there are any accompanying symptoms, such as pain, discharge, or changes in urination, these should be reported to the doctor as they can provide important clues to the underlying issue.

3. Communication with Your Partner:
- It is advisable to discuss any new symptoms with your partner, especially since they had a recent infection. Open communication can help both of you understand the situation better and decide if further medical evaluation is necessary for both parties.

4. Preventive Measures:
- Continue practicing safe sex by using condoms for all sexual activities, including oral sex, to minimize the risk of STIs.

- Regular STI screenings are recommended, especially if either partner has new symptoms or if there are changes in sexual health.

5. Conclusion:
- While the red bump could be benign, it is essential to seek medical advice to rule out any STIs or other infections. Early diagnosis and treatment can prevent complications and ensure both you and your partner maintain good sexual health.

In summary, while your consistent use of condoms significantly reduces the risk of STIs, it is still important to remain vigilant about any changes in your sexual health. Consulting a healthcare provider will provide you with the best course of action and peace of mind regarding your symptoms.
