STI Risks in Monogamous Same-Sex Relationships: Prevention Tips

Risk of Sexually Transmitted Infections (STIs)

Hello, doctor.
If I have a fixed, monogamous same-sex partner and our sexual life is straightforward, is there still a possibility of contracting HPV, amoebic dysentery, or poliovirus, among other sexually transmitted or fecal-oral transmitted diseases, during sexual intercourse? I found information indicating that asymptomatic individuals can still be carriers.
What should we be aware of during sexual activity? How can we prevent the transmission of these diseases? Thank you, doctor.

Hello! Partners can transmit existing diseases to each other through sexual intercourse or fecal-oral routes.
Therefore, if one partner has HPV or amoebiasis, it is certainly possible to transmit it to the other partner.
If both partners are in a monogamous relationship, there would naturally be no other sources for sexually transmitted infections.
Indeed, many diseases can be asymptomatic carriers, so for peace of mind, it is advisable for both partners to undergo health screenings to confirm whether either has any potential infectious diseases (which often one may not even be aware of).
It is still recommended to use condoms during sexual intercourse, as they can prevent over 90% of the transmission of infections.

In a monogamous same-sex relationship, the risk of sexually transmitted infections (STIs) can be significantly lower compared to relationships with multiple partners. However, it is important to understand that even in a committed relationship, there are still potential risks for STIs, including HPV (human papillomavirus), amoebic dysentery, and other infections that can be transmitted through sexual contact or fecal-oral routes.

Understanding STI Risks
1. Asymptomatic Carriers: Many STIs can be asymptomatic, meaning that individuals can carry and transmit infections without showing any signs or symptoms. This is particularly true for HPV, which can lead to serious health issues, including certain types of cancer, even in individuals who do not exhibit any symptoms.

2. Transmission Routes: STIs can be transmitted through various forms of sexual activity, including oral, anal, and vaginal intercourse. Additionally, infections such as amoebic dysentery can be transmitted through fecal-oral routes, which may occur during anal sex if proper hygiene is not maintained.

3. Potential Infections: In a same-sex relationship, the risk of infections like HPV, syphilis, gonorrhea, and chlamydia can still be present. While the risk is lower if both partners are monogamous and have been tested, it is crucial to remain vigilant.

Prevention Strategies
1. Regular Testing: Both partners should undergo regular STI screenings, even if they are in a monogamous relationship. This helps to identify any potential infections early on, especially since many STIs can be asymptomatic.

2. Vaccination: Vaccines are available for certain STIs, such as HPV. Getting vaccinated can significantly reduce the risk of contracting HPV and its associated complications.

3. Use of Condoms: While you may be in a monogamous relationship, using condoms during sexual activity can provide an additional layer of protection against STIs. Condoms are effective in reducing the transmission of many STIs, including HIV.

4. Communication: Open and honest communication with your partner about sexual health, past sexual history, and any concerns regarding STIs is vital. Discussing testing results and any symptoms can help both partners feel more secure.

5. Hygiene Practices: Maintaining good hygiene before and after sexual activity can help reduce the risk of infections. This includes washing hands and genital areas, especially if engaging in anal sex.

6. Limit Exposure: If either partner has had sexual encounters outside the relationship, it is essential to get tested before resuming sexual activity with each other. This helps to ensure that both partners are free from STIs.

Conclusion
In summary, while being in a monogamous same-sex relationship can lower the risk of STIs, it does not eliminate it entirely. Asymptomatic carriers can still pose a risk, and certain infections can be transmitted through various sexual activities. Regular testing, vaccination, condom use, and open communication are key strategies to minimize the risk of STIs. By taking these precautions, both partners can enjoy a healthier sexual relationship while reducing the likelihood of infection.
