I (male) recently had unprotected vaginal sex with someone who is much older than me and is very promiscuous in an urban area. I discussed STD risk with them and they claimed they were clean. I had a full STD test at 4 weeks, including a duo HIV antibody/antigen test, and another test at just under 6 weeks. Both came back negative, but I am having trouble moving on with the information on the internet. Any advice would help.
