I’m just getting quite anxious about whether or not I could have contracted the HIV virus. Last Friday, I entered a toilet cubicle (in a female bathroom at my workplace) as soon as another person came out and without checking whether there was anything on the toilet seat, I sat down and urinated. When I got up, I noticed that there were some red stains on the seat (which did not belong to me) and I was afraid that my butt might have come into direct contact with the blood on the seat, which could have been fresh. I know that the HIV virus can be contracted if fresh blood entered through broken skin/open wound but I was wondering what constitutes broken skin/open wound in the context of HIV transmission? I was wondering if I’m at any risk for HIV and if I should get tested for it?
