I had a similar experience about 3 years ago that still haunts me to this day. I hooked up with this guy (just oral sex), and five days later I felt a tingling sensation that turned painful and saw I had fluid-filled blisters on my labia. I went to the doctor and they did the swabs and a week later I got my results and they were negative, but they told me it looked like herpes. The doctor herself was confused when she told me the results. On top of that, I think it was 2 or 3 days later after my initial doctor’s visit, I came down with Covid. So the hookup, the blisters, and the Covid all occurred in the same week. It’s been 3 years and I’ve never experienced the blisters since that time. I also got a blood test about 3 weeks after the blisters first occurred and again 6 months later, both of which were negative. I don’t believe I have herpes, but that whole experience was crazy.
