Concerns After One-Night Stand: STD Testing and Risks Explained

I am starting to worry?

Hello Dr.
Liu, I had a one-night stand with a stranger yesterday, and it was my first time.
I won't go into details about the experience, but I regret it and I'm worried about sexually transmitted infections (STIs).
I have a few questions for you:
1.
How long should I wait before getting tested for STIs to ensure accurate results? I know that the incubation periods for HIV and syphilis are longer; how long should I wait to test for those two specifically?
2.
We used condoms during intercourse, but he performed oral sex on me.
What is the risk of transmission in this case?
3.
If a female patient performs oral sex on a male partner who is not infected, is there a high risk of contracting STIs?
4.
I live in Taipei; where can I go for a comprehensive STI screening?
Thank you.

1.
Visit a urologist at the hospital for a urine test within 7 to 10 days, and inquire about the timing for follow-up examinations.

2.
The risk is not high, but caution is still necessary.

3.
It depends on the specific condition affecting the female; saliva can contain the HIV virus, but at very low concentrations.

4.
You can consult the infectious disease, urology, and family medicine departments at major hospitals in Taipei City.

5.
Practice "safe sex" by using condoms throughout the entire sexual encounter.

It's understandable to feel anxious after a one-night stand, especially if it's your first experience. Let's address your concerns regarding STD testing and risks.

1. Timing for STD Testing: After a potential exposure to STDs, the timing of testing is crucial. For most STDs, testing can be done after a certain window period. For example:
- Chlamydia and Gonorrhea: Testing can be done about 1-2 weeks after exposure.

- Syphilis: Testing is recommended at 3 weeks after exposure, but it can take up to 6 weeks for accurate results.

- HIV: The window period can vary depending on the type of test. For the 4th generation HIV Ag/Ab test, you can test as early as 2 weeks, but it's best to wait 4-6 weeks for more reliable results. The CDC recommends testing again at 3 months for conclusive results.

- Herpes: If you suspect exposure, testing can be done about 2-3 weeks after, but for accurate results, it’s often recommended to wait 12 weeks.

2. Risk of Transmission During Oral Sex: While using a condom significantly reduces the risk of STDs during vaginal or anal sex, oral sex does carry some risk. The risk of transmission of STDs through oral sex is generally lower than through penetrative sex, but it is not zero. If the person performing oral sex has cuts or sores in their mouth, the risk increases. Additionally, STDs like gonorrhea and chlamydia can still be transmitted through oral sex.

3. Female to Male Oral Sex Risks: If a female performs oral sex on a male, there is a risk of transmission of STDs, particularly if there are any cuts or sores in the mouth. The risk is generally lower compared to vaginal or anal sex, but infections like gonorrhea, chlamydia, and herpes can still be transmitted. The presence of any oral lesions or bleeding gums can increase the risk.

4. Where to Get Tested in Taipei: In Taipei, there are several clinics and hospitals where you can get comprehensive STD testing. The Taipei City Health Department offers free or low-cost STD testing at designated clinics. Additionally, many private hospitals and clinics provide full STD panels. It's advisable to call ahead and inquire about the specific tests they offer and whether you need to make an appointment.

In conclusion, it's important to take your health seriously after a potential exposure to STDs. Getting tested is a responsible step, and understanding the risks associated with different sexual activities can help you make informed decisions in the future. If you're feeling overwhelmed, consider speaking with a healthcare professional who can provide guidance and support. Remember, many STDs are treatable, and early detection is key to effective management. Don't hesitate to reach out for help and support as you navigate this situation.
