When it comes to understanding the risks associated with sexually transmitted infections (STIs) such as syphilis and HPV (human papillomavirus), it is crucial to consider the nature of the sexual activities involved, the presence of protective measures, and the timing of testing.

Firstly, regarding your concern about syphilis, you mentioned that you had a blood test for syphilis (RPR) at 28 days post-exposure, and the result was negative. Generally, the RPR test can detect syphilis infection within a few weeks after exposure, but it is not definitive until about 6 weeks post-exposure. While a negative result at 28 days is a good sign, it does not completely rule out the possibility of infection, especially if the exposure was recent. It is advisable to follow up with another test at around 6 weeks to ensure that you have accurately ruled out syphilis.

Now, regarding your concerns about HPV and the specific sexual activities you described, it is important to understand how HPV is transmitted. HPV is primarily spread through skin-to-skin contact during sexual activities, including vaginal, anal, and oral sex. The risk of transmission can vary based on several factors, including the type of HPV, the presence of any visible warts (condylomata), and whether any protective measures were used.

In your case, you mentioned engaging in unprotected hand and breast contact, with no direct contact between the penis and the partner's genitalia or saliva. While the risk of HPV transmission through these activities is lower compared to penetrative sex, it is not zero. HPV can be present on the skin and can potentially be transmitted through indirect contact if the virus is present on the hands or other body parts. However, the likelihood of contracting HPV through the activities you described is relatively low, especially since you have completed the three doses of the HPV vaccine, which provides protection against the most common high-risk HPV types associated with cervical cancer and genital warts.

It is also worth noting that the HPV vaccine is highly effective in preventing infections from the types of HPV it covers, including HPV 6 and 11, which are responsible for most cases of genital warts. Since you have been vaccinated, your risk of developing condylomata (genital warts) is significantly reduced.

If you are still concerned about potential HPV infection, it may be beneficial to consult with a healthcare provider about HPV testing. However, routine HPV testing is generally not recommended for individuals under 30 unless there are specific symptoms or concerns, as many HPV infections clear on their own without causing any health issues.

In summary, while your risk of contracting syphilis appears low based on your negative RPR test, it is advisable to retest at the appropriate time for peace of mind. Regarding HPV, the activities you described present a lower risk, especially considering your vaccination status. If you have any further concerns or symptoms, it is always best to consult with a healthcare professional for personalized advice and potential follow-up testing.
