Between 3rd March 2013 to 14th March 2013 I had protected vaginal sex 4 times with with a CSW. On 14th March I also performed unprotected cunnilingus on her with my tongue and inner part of lower lip.
On 26th March 2013 I had 4th generation DUO test and a an HIV-1 RT-PCR qualitative test. Both came negative.
The CSW I gave cunnilingus to was OK if chose not to use a condom. Also recently I got to know that she has been sick with bouts of flu.
What are my chances of being HIV positive? Do i need additional testing?
