Can oral sex transmit sexually transmitted infections (STIs)?


How can one contract a sexually transmitted infection (STI)? Is it dangerous if someone engages in sexual activity once or twice a week? If oral hygiene is maintained, is there still a risk of contracting an STI?

Hello: If a sexual partner has a sexually transmitted infection (STI), there is a possibility of transmission.
You can refer to https://www.cdc.gov.tw/info.aspx?treeid=45DA8E73A81D495D&nowtreeid=1BD193ED6DABAEE6&tid=3C8135237F4A4041 for more information.

Oral sex can indeed transmit sexually transmitted diseases (STDs), and understanding the risks associated with it is crucial for maintaining sexual health. While many people may perceive oral sex as a safer alternative to vaginal or anal intercourse, it is important to recognize that it is not without risks.
Firstly, STDs can be transmitted through oral sex when there is direct contact with infected bodily fluids, such as semen, vaginal fluids, or blood. This means that even if you are not engaging in penetrative sex, you can still be at risk if you perform oral sex on a partner who has an STD. Common STDs that can be transmitted through oral sex include gonorrhea, chlamydia, syphilis, herpes, and human papillomavirus (HPV).
The risk of transmission can be influenced by several factors, including the presence of cuts or sores in the mouth, gum disease, or any other oral health issues. For instance, if a person has bleeding gums or oral lesions, the risk of contracting an STD increases significantly. Additionally, certain STDs can also manifest symptoms in the throat, leading to conditions such as pharyngeal gonorrhea or herpes.

Regarding your question about the frequency of engaging in oral sex, doing it once or twice a week does not inherently increase your risk of contracting an STD, provided that both you and your partner are free of infections. However, if either partner has an STD, the risk of transmission remains, regardless of the frequency of sexual activity. Regular testing for STDs is essential, especially if you have multiple partners or if you are unsure of your partner's sexual health status.

Maintaining good oral hygiene is important, but it does not eliminate the risk of STD transmission. Even with clean oral health, the presence of an infection in a partner can still pose a risk. Therefore, using protection, such as condoms or dental dams, during oral sex can significantly reduce the risk of STD transmission. These barriers help prevent direct contact with bodily fluids and can protect against infections.

In summary, while oral sex is often considered a lower-risk sexual activity compared to vaginal or anal sex, it is not risk-free. The potential for STD transmission exists, particularly if one partner is infected. It is essential to communicate openly with partners about sexual health, practice safe sex by using barriers, and get regularly tested for STDs to ensure both your health and the health of your partners. If you have concerns about your sexual health or potential exposure to STDs, consulting a healthcare provider for personalized advice and testing is always a wise decision.
