When it comes to understanding the risks of syphilis and other sexually transmitted infections (STIs) associated with oral sex and kissing, it's essential to consider several factors, including the nature of the sexual activities, the presence of any sores or cuts, and the STI status of both partners.

Firstly, oral sex is classified as a medium-risk sexual activity for the transmission of STIs, including syphilis. This classification is due to the potential for contact with bodily fluids, which can harbor pathogens. Syphilis, in particular, is caused by the bacterium Treponema pallidum, which can be transmitted through direct contact with syphilis sores, which may be present on the genitals, anus, or mouth of an infected person. If you engaged in oral sex without any barriers (like condoms or dental dams), there is a risk of transmission if your partner is infected.

Kissing, especially deep kissing, can also pose a risk for certain infections, particularly those that can be transmitted through saliva. While syphilis is less commonly transmitted through kissing compared to oral sex, it is still possible if there are open sores or lesions in the mouth. The presence of cuts or abrasions in your mouth or on your partner's can increase the risk of transmission.

In your case, since you mentioned that there were no visible sores on your oral cavity or genital area, this may reduce the risk somewhat. However, it is important to note that many STIs can be asymptomatic, meaning that an infected person may not show any signs or symptoms but can still transmit the infection to others.
The risk of contracting syphilis or other STIs through oral sex and kissing is influenced by the STI status of your partner. If your partner has syphilis or another STI, the risk of transmission increases significantly. Therefore, knowing your partner's sexual health status is crucial. Regular STI testing and open communication about sexual health are essential practices for anyone who is sexually active.

In terms of infection probability, while it is difficult to quantify exact risks without specific data, the general consensus in the medical community is that engaging in unprotected oral sex does carry a risk of STI transmission. If you have concerns about potential exposure to syphilis or other STIs, it is advisable to consult a healthcare provider for testing and further evaluation.
In summary, while the risk of contracting syphilis through oral sex and kissing exists, it is influenced by several factors, including the presence of sores, the STI status of both partners, and the type of sexual activities engaged in. Practicing safer sex, including the use of barriers and regular STI screenings, can significantly reduce the risk of transmission. If you experience any symptoms or have concerns about potential exposure, seeking medical advice is the best course of action.
