When it comes to understanding the risks of HIV transmission during sexual activity, especially when using condoms, it's essential to consider several factors, including the integrity of the condom, the nature of the sexual act, and the characteristics of the condom itself.

1. Condom Integrity and HIV Transmission Risk: If you used a condom throughout the sexual encounter and it did not break or slip off, the risk of HIV transmission is significantly reduced. Condoms are designed to act as a barrier to prevent the exchange of bodily fluids, which is the primary mode of HIV transmission. If there was no visible blood on the condom and the condom remained intact, the likelihood of HIV transmission is very low. However, it is important to note that while condoms are highly effective, they are not 100% foolproof. Factors such as improper use, damage during application or removal, and the presence of pre-ejaculate fluid can influence the risk.
2. Condom Fit and Effectiveness: Regarding the size of the condom, a proper fit is crucial for both comfort and effectiveness. You mentioned that your penis circumference is 11 cm and you are using a condom with a width of 52 mm. Generally, a condom width of 52 mm is considered standard and should fit most men comfortably. However, if the condom feels too loose, it may increase the risk of slippage during intercourse, which can lead to exposure to bodily fluids. A condom that is too tight can also break, which is another risk factor. It is essential to choose a condom that fits well; if you find that the 52 mm width feels too loose, you might want to consider trying a narrower size to ensure a snug fit.

3. Understanding HIV Risks: The risk of HIV transmission is influenced by several factors, including the viral load of the HIV-positive partner, the presence of other sexually transmitted infections (STIs), and the type of sexual activity. For example, anal sex carries a higher risk of transmission compared to vaginal sex. Additionally, if the HIV-positive partner is on effective antiretroviral therapy and has an undetectable viral load, the risk of transmission is significantly reduced, a concept often summarized by the phrase "Undetectable = Untransmittable" (U=U).

4. Testing and Monitoring: If you have concerns about potential exposure to HIV, it is advisable to get tested. The window period for HIV tests can vary, but many tests can provide accurate results within a few weeks after exposure. Regular testing is a good practice, especially if you have multiple partners or engage in high-risk behaviors.

5. Conclusion: In summary, if you used a condom correctly and it remained intact throughout the encounter, the risk of HIV transmission is very low. However, ensuring a proper fit is essential for maximizing protection. If you have any lingering concerns or symptoms, consulting a healthcare professional for personalized advice and testing is always a prudent step. Remember, practicing safe sex and regular health check-ups are key components of maintaining sexual health.
