Unprotected oral sex without ejaculation?


1.
On September 26, I performed unprotected oral sex on a man.
He did not ejaculate during the act, which lasted no longer than 2 minutes.
However, starting on September 28, I began to experience a sore throat and pain when swallowing.
I am concerned about the possibility of contracting a sexually transmitted infection (STI).
2.
The man's penis showed no signs of sores or wounds; it appeared normal and had no unusual odor.
Is it necessary for a person with an STI to have sores on their genitals?

Niming, 20~29 year old female. Ask Date: 2020/09/29

Dr. Cai Zhuorong reply Urology


Not necessarily; individuals with sexually transmitted infections (STIs) do not always have genital ulcers.
For example, infections like gonococcal urethritis may present with discharge but do not typically cause ulcers.

Engaging in oral sex without protection does carry certain risks for sexually transmitted infections (STIs), and it’s important to understand these risks, especially in the context of your recent experience.
1. Understanding the Risks: Oral sex can transmit STIs, including gonorrhea, chlamydia, syphilis, and herpes, among others. While the risk of transmission through oral sex is generally lower compared to vaginal or anal sex, it is not negligible. The presence of any cuts, sores, or abrasions in the mouth or throat can increase the risk of transmission. In your case, the fact that you performed oral sex without a condom does mean there is a potential risk, even if the encounter was brief and the partner did not ejaculate.

2. Symptoms and Their Implications: You mentioned experiencing a sore throat starting two days after the encounter. A sore throat can be a symptom of several conditions, including viral infections (like the common cold), bacterial infections (like strep throat), or STIs (like gonorrhea or herpes). The timing of your symptoms is noteworthy; while it is possible for STIs to present symptoms within a couple of days, it is also common for viral infections to cause similar symptoms.
3. Infection Without Visible Symptoms: Regarding your question about whether a person with an STI must have visible sores or wounds on their genitals, the answer is no. Many STIs can be asymptomatic, meaning that individuals can carry and transmit infections without showing any signs or symptoms. For example, chlamydia and gonorrhea often do not present any visible symptoms in the genital area, and individuals may be unaware they are infected.
4. Next Steps: Given your symptoms and the nature of your encounter, it would be prudent to seek medical advice. A healthcare provider can perform appropriate tests to determine if you have contracted an STI. It’s also important to communicate openly with any sexual partners about potential risks and to consider regular STI screenings if you are sexually active.

5. Preventive Measures: Moving forward, using protection during oral sex, such as condoms or dental dams, can significantly reduce the risk of STI transmission. Additionally, avoiding oral sex immediately after brushing your teeth or flossing (to prevent bleeding gums) is a good practice, as it can create entry points for infections.

In conclusion, while the risk of contracting an STI from a brief episode of unprotected oral sex is lower than other forms of sexual activity, it is not zero. The presence of symptoms like a sore throat warrants further investigation, and it’s advisable to consult a healthcare professional for testing and guidance. Regular screenings and safe sex practices are essential in maintaining sexual health and preventing the spread of STIs.
