Oral Sex and Its 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 the higher presence of viruses in the genital area compared to the mouth, or is there a possibility of a sexually transmitted infection?

Dr. Liu Mingyue reply Urology


Hello: Since 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 you provided.
I would not immediately consider sexually transmitted infections (STIs) that are more commonly associated with same-sex relationships.
The key point is whether your partner has any sexually transmitted diseases.
Several STIs 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 risks associated with oral sex, particularly in the context of same-sex relationships, is crucial for maintaining sexual health. Oral sex, while often perceived as a safer alternative to penetrative sex, still carries significant risks for sexually transmitted infections (STIs), including but not limited to HIV, herpes, syphilis, gonorrhea, and chlamydia.

In your case, the symptoms you described—white lesions under the tongue after performing oral sex—could indicate several possibilities. These lesions may be a result of an oral infection, which can occur due to various pathogens, including viruses and bacteria. The presence of these lesions following oral sexual contact raises the question of whether they could be related to an STI.

1. Transmission of STIs through Oral Sex: Oral sex can transmit STIs, especially if one partner has an active infection. For instance, herpes simplex virus (HSV) can be transmitted through oral-genital contact, leading to oral or genital lesions. Other infections, such as gonorrhea and syphilis, can also be transmitted through oral sex. Therefore, it is essential to consider the sexual health status of your partners. If any of them had an STI, there is a possibility that you could have contracted it through oral sex.

2. Oral Infections: The white lesions you are experiencing could also be due to a non-STI-related oral infection, such as oral thrush (a fungal infection) or a reaction to irritation or trauma. If you recently brushed your teeth vigorously or had any cuts or abrasions in your mouth, this could also lead to secondary infections. However, given your sexual history, it is prudent to consider the possibility of an STI.

3. Importance of Communication and Testing: It is vital to communicate openly with your sexual partners about STI testing and sexual health. Regular testing for STIs is recommended, especially for individuals with multiple partners or those engaging in higher-risk sexual behaviors. If you have not already done so, consider getting tested for STIs, even if you do not exhibit symptoms. Many STIs can be asymptomatic, meaning individuals may not show any signs of infection but can still transmit the virus to others.

4. Consulting a Healthcare Provider: Since you have already seen a doctor who attributed your symptoms to an oral infection without considering your sexual history, it may be beneficial to seek a second opinion. When you visit a healthcare provider, be transparent about your sexual activities and any symptoms you are experiencing. This information will help them provide a more accurate diagnosis and appropriate treatment.

5. Preventive Measures: To reduce the risk of STI transmission during oral sex, consider using barriers such as condoms or dental dams. These can significantly lower the risk of transmitting infections. Additionally, maintaining good oral hygiene and avoiding oral sex when you or your partner have visible sores or infections can help minimize risks.

In conclusion, while oral sex is often viewed as a lower-risk sexual activity, it is not without its dangers, particularly in the context of STIs. Given your symptoms and sexual history, it is essential to take proactive steps, including getting tested and communicating with your partners about sexual health. Always prioritize your health and safety in sexual relationships.
