When it comes to understanding HIV risks and safe practices during sexual encounters, it's essential to consider various factors that influence the likelihood of transmission. Here’s a comprehensive response to your questions:
1. Risk of HIV Transmission with Condom Use: If you engaged in sexual activity with a sex worker and used a condom throughout the encounter, the risk of contracting HIV is significantly reduced. Condoms are highly effective at preventing the transmission of HIV and other sexually transmitted infections (STIs) when used correctly and consistently. Studies indicate that when condoms are used properly, they can reduce the risk of HIV transmission by approximately 80-95%. Therefore, if you used a condom throughout the entire sexual encounter, the likelihood of contracting HIV is low.

2. Assuming the Sex Worker is HIV Positive: If we assume that the sex worker is HIV positive, using a condom still provides a substantial level of protection. While no method is 100% effective, the use of condoms can lower the risk of HIV transmission to less than 1% per act of intercourse when used correctly. This is a significant reduction compared to unprotected sex, where the risk can be much higher, especially if there are other factors such as the presence of cuts or sores, or if the HIV-positive individual has a high viral load. Therefore, using a condom greatly diminishes the risk of infection compared to not using one.

3. Oral Sex with Condom Use: Regarding oral sex, if the female partner performed oral sex on you while you were wearing a condom, the risk of HIV transmission is extremely low. The primary concern with oral sex is the potential for transmission through cuts or sores in the mouth, but if there are no open wounds and the condom is intact, the risk remains minimal. The presence of saliva also helps to dilute any potential viral load, further reducing the risk.
In summary, the use of condoms is one of the most effective ways to prevent HIV transmission during sexual encounters. It is crucial to ensure that condoms are used correctly and consistently. Here are some additional safe practices to consider:
- Regular Testing: Regular testing for HIV and other STIs is essential for sexually active individuals, especially if engaging with multiple partners. Knowing your status and that of your partners can help in making informed decisions about sexual health.

- Pre-Exposure Prophylaxis (PrEP): For individuals at higher risk of HIV exposure, PrEP is a preventive medication that can significantly reduce the risk of contracting HIV when taken consistently.

- Post-Exposure Prophylaxis (PEP): If you believe you have been exposed to HIV, PEP can be taken within 72 hours after potential exposure to reduce the risk of infection. It is crucial to seek medical advice immediately in such cases.

- Communication: Open communication with sexual partners about sexual health, testing history, and safe practices is vital in reducing risks.

- Avoiding Substance Use: Avoiding drugs and alcohol during sexual encounters can help maintain clear judgment and make safer choices regarding sexual practices.

In conclusion, while the risk of HIV transmission can never be entirely eliminated, following safe practices, including the consistent use of condoms, regular testing, and considering preventive medications, can significantly reduce the likelihood of infection. If you have any further concerns or experience symptoms, it is advisable to consult a healthcare professional for personalized advice and testing.
