Concerns About Oral Infection After Recent Sexual Activity - Urology

Concern about infection?


Doctor, I apologize for bothering you.
About three days ago, I had oral sex with my boyfriend, and he ejaculated in my mouth, but I immediately spit it out.
However, I then drank hot water, and there was no other sexual activity afterward.
In the following two to three days, I experienced gum pain while brushing my teeth, and there was also slight discomfort in the area of my tonsils.
Today, three days after the sexual activity, the left corner of my mouth is a bit swollen and numb.
I'm very worried about the possibility of an infection.
I'm sorry to trouble you with this.

After engaging in oral sex, especially when bodily fluids are involved, it's natural to have concerns about potential infections. Your symptoms, including gum pain, discomfort in the tonsil area, and swelling at the corner of your mouth, could be indicative of several conditions, including infections or irritations.

Firstly, it's important to understand that oral sex can indeed pose a risk for sexually transmitted infections (STIs), including herpes, gonorrhea, chlamydia, and syphilis. The risk is heightened if there are any cuts or abrasions in the mouth or throat, as these can serve as entry points for pathogens. In your case, the pain in your gums and the discomfort in your tonsils could suggest an oral infection, which might be viral or bacterial in nature.

The fact that you experienced pain in your gums while brushing your teeth could indicate gingivitis or another form of gum disease, which can be exacerbated by oral sexual activity. Additionally, the swelling at the corner of your mouth might suggest angular cheilitis, which can occur due to irritation, fungal infections, or even nutritional deficiencies.

Given that you mentioned your partner ejaculated in your mouth, there is a possibility of exposure to various pathogens. However, the immediate onset of symptoms (within a few days) is more commonly associated with viral infections, such as herpes simplex virus (HSV), which can cause oral herpes. Symptoms of oral herpes can include sores, swelling, and discomfort in the mouth, and they can sometimes be mistaken for other conditions.

It's also worth noting that if your partner has any oral lesions or infections, this could increase the risk of transmission. If they were experiencing any symptoms of an STI, it would be prudent for both of you to get tested.
In terms of your concerns about infection, while it's possible to contract an STI through oral sex, the likelihood varies based on several factors, including the presence of sores, the type of sexual activity, and the overall health of both partners. The symptoms you are experiencing do not definitively indicate an STI, but they warrant further investigation.

I recommend that you see a healthcare provider for a thorough examination. They may suggest testing for common STIs, especially if your symptoms persist or worsen. Additionally, they can assess your oral health and provide treatment for any infections or conditions that may be present.

In the meantime, maintaining good oral hygiene is crucial. Avoid any irritants, such as spicy or acidic foods, and consider using a saltwater rinse to soothe your gums. If you notice any new symptoms, such as fever, increased swelling, or the development of sores, seek medical attention promptly.

In summary, while your symptoms could be related to an infection, they are not exclusively indicative of an STI. A healthcare professional can provide a more accurate diagnosis and appropriate treatment based on a comprehensive evaluation of your symptoms and medical history.
