You may be almost within the guidelines for frequency of posting new questions on the professionally moderated forums. However, another rule prohibits repeated anxiety driven questions that are similar to previous ones -- regardless of frequency.
You had a low risk exposure, since it is unlikely your CSW partner has HIV (both because most CSWs aren't infected, and mostly they don't lie if they are); even if she had it, the average transmission risk for a single vaginal sex exposure is around 1 in 2,000; and most important, the rapid HIV blood tests are virtually 100% reliable at 6 weeks. It really isn't necessary to wait until 12 weeks to be certain, especially since your risk was so low that HIV testing really wasn't even required. See the thread linked below for more information about time to reliable HIV test results.

Based on the information you have provided, you can safely have unprotected sex without fear of infecting her with HIV.
