About 2 months ago I (male) received oral sex from a girl of unknown status. 2 weeks after exposure I was tested for chlamydia, gonorrhea and syphilis and all came back negative. At the 7 week mark post exposure I also got a 4th generation antibody/antigen HIV test which came back negative. I asked her if I had anything to worry about and she said no but obviously you never know. I have started to date someone since and am nervous to become sexually active with her if I have something. I have not had any sores or discharge.
1. Should I get retested for HIV or is 7 week test for antibody/antigen conclusive?
2. I have read that herpes can show no symptoms should I get tested with no symptoms?
3. Knowing my risk and testing should I be worried to do anything with my current GF or should I get retested first?
Thank you for the help.
