I contracted an STI in my penis after brief unprotected MSM anal sex in June 2013. I was prettty drunk at the time.
The STI was treated successfully but, one month later, I had unusual symptoms: severe diarrhoea, sweating and reddening of skin. The diarrhoea only lasted for 3 days, the other symptoms have persisted on and off.
I have had lab HIV tests 2, 6, 8, 12, 16, 21 and 25 weeks after the possible exposure. I also has rapid blood tests after 8 and 10 months.
All of these tests have been HIV negative.
I have not had any sexual contact with anyone since the risky exposure and remain concerned that the testsmay have missed HIV infection. I have read about people taking a very long time to test positive.
Do I have any reason to still be worried?
