Hello, recently I had sex with a prostitute in the dominican, an area that has high HIV prevelence. I used a condom, and finished outside of her, and was not in her for long. I am not sure whether the condom was on fully, however I am sure that it did not break, cuz i saw it when i took it out. I am still worried however about the chances that I could be at risk for transmission. Please let me know
