I recently had a sexual encounter with a female. We had sex briefly (literally about ten seconds) and I wore a condom. In the morning, she performed oral sex.
A week later I developed an ulcer and swelling on the shaft of the penis. I take minocycline (antibiotic) for acne, but had not taken it for about one month. I started taking it a couple days after the sore and swelling appeared, and both subsided within 3 days.
It has been almost five weeks since my encounter. I have not had any fever or noticed any enlargement of my lymph nodes. I did have a sore throat for a couple days recently, but that passed. Is a genital ulcer and swelling alone a common symptom of HIV?
