I met a 40-year-old lady in Dubai, and she ended up performing oral sex on me. I was wearing a condom, but at one point, I sucked on her left nipple for maybe a minute. I'm not sure about her HIV status; she seemed like a prostitute. I can't really remember if any breast discharge got into my mouth, but right after, I rinsed my mouth with water. Then, about five minutes later, I brushed my teeth with toothpaste and swallowed. I'm really concernedcould I have contracted HIV from this encounter? It's been 71 days now, and I had two different rapid tests, both came back negative. Should I be worried about getting infected?
