Oral Sex and Its Potential Risks: What You Need to Know - Urology

Oral sex virus


I would like to ask the doctor, I have only had sexual relations with four men, but there was no penetrative sexual intercourse, only oral sex and kissing.
However, I noticed that after performing oral sex on two of them, white lesions appeared under my tongue a few days later, which are not very painful.
I previously visited a doctor who was unaware of my sexual activity and simply diagnosed it as an oral infection.
Could this be due to a higher presence of viruses between the genital area and the mouth, or is it possible that I could have contracted a sexually transmitted infection?

Hello: Because your symptoms occurred after oral sex and kissing, if I were your treating physician, I could only suspect an infection due to the lack of information provided.
I would not immediately consider sexually transmitted infections (STIs) that are more commonly transmitted through same-sex relationships.
The key point is whether your partner has any STIs, as several sexually transmitted diseases can be transmitted through oral sex and kissing.
I personally recommend that if your condition does not improve after treatment, you should return for a follow-up and provide your physician with relevant information.
There are still some situations that need to be considered.
Wishing you good health.

Understanding the potential risks associated with oral sex is crucial for maintaining sexual health, especially in the context of same-sex relationships. Oral sex, while often perceived as a safer alternative to penetrative sex, still carries certain risks for sexually transmitted infections (STIs).
Firstly, it's important to recognize that oral sex can transmit various STIs, including but not limited to gonorrhea, chlamydia, syphilis, and human immunodeficiency virus (HIV). The risk of transmission is influenced by several factors, including the presence of cuts or sores in the mouth, the viral load of an infected partner, and the type of sexual practices engaged in. For instance, if you have oral lesions or cuts, the likelihood of contracting an infection increases significantly when engaging in oral sex with an infected partner.

In your case, the appearance of white lesions under your tongue after performing oral sex could indicate an oral infection, which may or may not be related to an STI. Conditions such as oral thrush (a fungal infection) or herpes simplex virus can present with similar symptoms. It's also possible that these lesions are a result of irritation or trauma from the sexual activity itself, especially if there was vigorous movement or friction.

The fact that you have engaged in oral sex with multiple partners raises the concern of potential STI exposure. While you mentioned that there was no penetrative sex involved, oral sex can still facilitate the transmission of infections. The presence of saliva, which can carry pathogens, means that even without direct contact with genital secretions, there is still a risk of transmission.
To address your concerns about whether the lesions are due to a higher concentration of viruses in the genital area compared to the mouth, it’s essential to understand that both areas can harbor pathogens. The mouth is not immune to infections, and certain STIs can thrive in oral mucosa. Therefore, it is plausible that the lesions could be a result of an STI, particularly if you have had unprotected oral sex with partners who may have been infected.

Given your symptoms and the context of your sexual history, it is advisable to seek further medical evaluation. A healthcare provider can conduct specific tests to determine if you have an STI or another type of oral infection. It’s also important to be open about your sexual history with your healthcare provider, as this information can guide them in making an accurate diagnosis.

In addition to seeking medical advice, consider implementing safer sex practices moving forward. This includes using barriers such as condoms or dental dams during oral sex to reduce the risk of STI transmission. Regular STI screenings are also recommended, especially if you have multiple partners or engage in high-risk sexual behaviors.
In conclusion, while oral sex is often viewed as a lower-risk sexual activity, it is not without its dangers. The symptoms you are experiencing warrant further investigation to rule out any infections, including STIs. Open communication with healthcare providers and practicing safer sex can significantly reduce your risk of infections and promote better sexual health.
