Hello, last year I had protected sex with a Korean CSW, but my balls got wet and I didn't realize this until much later. I don't know if my urethra rubbed up against my balls. A few days after I had a bad cough that subsided after a few days. I tested negative at 6 months, 10 months, 12 months, and 14 months but I have a swollen lymph node near my ear for the past 6 months. Have there been any cases where someone doesn't make antibodies against HIV? Should I get a RNA PCR? The lymph node swelling is small but noticable.
