The risk of sexually transmitted infections (STIs) through oral sex between couples?


Hello Dr.
Lee, a few days ago my girlfriend performed oral sex on me, and now I am concerned about the possibility of transmitting a sexually transmitted infection (STI) to her, especially since she has periodic oral ulcer symptoms.
When these symptoms appear, is it advisable to avoid oral sex? I would like to ask if both of us being each other's first sexual partners means that we do not need to worry about the risk of STI transmission?

If neither of you has any sexually transmitted infections, then there is no need to worry about STDs.
It is advisable for your girlfriend to see a doctor as soon as she discovers the oral ulcer to check if it is a herpes simplex virus infection, and then discuss it with the doctor.

When it comes to oral sex and the associated risks of sexually transmitted diseases (STDs), it is essential to understand the dynamics of transmission and the factors that can influence the likelihood of infection. Oral sex, while often perceived as a safer alternative to penetrative sex, still carries risks for the transmission of various STDs, including herpes, gonorrhea, syphilis, and human papillomavirus (HPV).

In your case, both you and your girlfriend are each other's first sexual partners, which may reduce the risk of having an STD, assuming neither of you has had prior sexual encounters that could have exposed you to infections. However, it is crucial to consider that some STDs can be asymptomatic, meaning that one partner may carry an infection without showing any visible symptoms. This is particularly true for infections like chlamydia and gonorrhea, which can infect the throat through oral sex.

Regarding your girlfriend's recurring oral ulcers, it is wise to consult a healthcare professional. While these ulcers may be due to non-STD-related causes, such as canker sores or viral infections like herpes simplex virus (HSV), it is essential to rule out any potential STD. If she has a history of oral herpes, for instance, it could be a factor in the development of these ulcers. If she has active lesions, it is advisable to avoid oral sex until she has been evaluated and treated, as this can significantly reduce the risk of transmission.

In terms of the safety of oral sex during these symptoms, it is generally recommended to avoid oral contact if either partner has visible sores or ulcers in the mouth or genital area. This is because these lesions can harbor infectious agents, increasing the likelihood of transmission.
Moreover, even if both partners are new to sexual activity, it is still prudent to engage in safe practices. Using barriers such as condoms or dental dams during oral sex can help reduce the risk of STD transmission. Regular testing for STDs, especially if either partner has had other sexual encounters in the past, is also a good practice to ensure both partners are aware of their sexual health status.

In summary, while the risk of STD transmission may be lower between two individuals who are each other's first partners, it is not zero. The presence of oral ulcers in your girlfriend warrants further investigation, and it is advisable to avoid oral sex until a healthcare provider can assess the situation. Practicing safe sex, including the use of barriers and regular testing, can help mitigate risks and promote a healthy sexual relationship. Always prioritize open communication with your partner about sexual health and any concerns that may arise.
