? Should I be worried? I was tested for all STI 2 months back and tested NEG for everything, and I always practice safe sex, but i'm still worried. If she WAS infected with HIV, would testing be required based on this instance? Thanks.
The same risk that you would have if she were not infected: ZERO. The anal sex was protected.
"Should I be worried?"
No.
"If she WAS infected with HIV, would testing be required based on this instance?"
No.
Just an FYI: wearing more than one condom actually increases the chances that both will break due to the friction between them. It is safest to wear just one condom and use plenty of lube to minimize the chance of breakage.
