Sexually transmitted diseases (STDs) issues?


Hello Doctor: I am a 23-year-old male.
Two days ago, I had sexual contact with a 16-year-old female who previously engaged in sex work.
The actions included: kissing for about 5 seconds, using a condom on my penis at the vaginal opening or slightly deeper without full penetration, and fully inserting my fingers into her vagina.
Since the female has a history of sex work, I am concerned about the risk of sexually transmitted infections (STIs), including HIV/AIDS.
After the encounter, I did some research on AIDS and it seems that the act of finger insertion into the vagina poses a higher risk due to contact with vaginal secretions.
I checked my fingers for any cuts, and it appears there are no wounds on the part of the fingers that were fully inserted into the vagina.
However, there is a small red dot, less than 0.1 cm in diameter, located about 2 cm below the connection point of my fingers and palm.
This red dot did not sting when I washed my hands, and it does not seem to be a deep wound.
I would like to ask the doctor: 1.
Based on the description of the small wound on my palm, is there a chance of contracting AIDS if the female is HIV positive? 2.
I read online that there have been no documented cases of HIV transmission through saliva unless there is a significant amount (like 8 liters) or if there are wounds in the mouth.
I currently feel that my mouth has no wounds.
Is there a risk of contracting AIDS from the kiss? Thank you for your response, Doctor.

Hello, actually, the concerns you have cannot be definitively answered.
For you, it is either a matter of having it or not having it.
Any contact with bodily fluids theoretically carries the risk of acquiring HIV.
If there are open wounds, the risk increases.
However, the virus itself can be eliminated outside the body simply by using soap and water.
If you have serious doubts, you can visit the Centers for Disease Control website, where you can find a list of anonymous STD testing facilities that offer services completely free of charge.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
This response is from Dr.
Hsu Wei-kai, Chief of Urology, Taitung Hospital, Department of Health, Executive Yuan.

When it comes to understanding the risks of sexually transmitted diseases (STDs), especially in the context of recent sexual encounters, it's important to assess the specific behaviors involved and the potential for transmission. Based on your description, let's break down the risks associated with your actions and provide guidance on what steps to take next.

1. Understanding the Risks of Your Actions:
- Kissing: Engaging in a brief kiss (like the 5-second tongue kiss you mentioned) carries a very low risk for HIV transmission. While HIV can be present in saliva, the concentration is extremely low, and transmission through kissing is virtually unheard of unless there are open sores or bleeding gums involved. Since you indicated that you did not have any noticeable wounds in your mouth, the risk from kissing is negligible.


- Vaginal Penetration with a Condom: Using a condom significantly reduces the risk of transmitting HIV and other STDs during vaginal intercourse. However, you mentioned that the penetration was not deep and that you were using a condom. If the condom was intact and used correctly, the risk of HIV transmission is low. It's essential to ensure that the condom is properly fitted and that it does not slip or break during intercourse.

- Digital Penetration (Finger Insertion): This is where the risk can increase, especially if there is any potential for contact with vaginal fluids. You noted a small red dot on your palm, which raises a concern. If this area was not bleeding and the injury is superficial, the risk of HIV transmission through a small cut is still low, but it is not zero. If the female partner is HIV positive, there is a theoretical risk, but it is significantly lower than with unprotected vaginal intercourse.

2. Assessing the Small Red Dot:
- The small red dot you described does not seem to indicate a significant risk for HIV transmission, especially if it is not deep and does not bleed. However, it is always wise to err on the side of caution. If you are concerned about any potential exposure, consider consulting a healthcare professional for a thorough evaluation.

3. Post-Exposure Prophylaxis (PEP):
- If you are particularly worried about potential HIV exposure, you may want to discuss the option of PEP with a healthcare provider. PEP is a course of antiretroviral medication that can reduce the risk of HIV infection if taken within 72 hours after a potential exposure. It is most effective when started as soon as possible.

4. Testing for STDs:
- Regardless of the perceived risk, it is advisable to get tested for STDs after any new sexual encounter, especially with a partner who has a history of sex work. The CDC recommends routine screening for sexually active individuals, particularly for those with multiple partners or those who engage in higher-risk behaviors. Testing can provide peace of mind and ensure that any potential infections are caught early.

5. Follow-Up:
- If you experience any symptoms such as unusual discharge, sores, or flu-like symptoms in the weeks following your encounter, seek medical attention promptly. Many STDs can be asymptomatic, so regular testing is crucial.

In summary, while your described actions carry some risk, the likelihood of contracting HIV from the encounter you described appears to be low, particularly due to the use of a condom and the nature of the contact. However, it is always best to consult with a healthcare provider for personalized advice and to consider testing for STDs as a precautionary measure. Taking these steps will help you manage your health and alleviate concerns about potential infections.
