Patient's question:
Going to a relative's house (where the relatives' friends also live) to use the restroom, I had a bowel movement and sat on the toilet. I noticed what looked like a bloodstain on the inside of the toilet bowl, but I didn't know where it came from. At the time, I didn't pay attention if my penis touched it. If it did, would I get infected? It didn't seem to have any bloodstains on it. Also, I don't think I was erect at the time, so my foreskin was mostly still covering it. Could I still get infected? I'm really worried now. I'm only 13~~~Doctor's answer:
Generally, it's not a big deal, as the chance of transmission is extremely low. Advice: If your friend is a decent person, they are unlikely to have HIV, so transmission is absolutely impossible. Even if your friend does have HIV, this type of contact is less likely to result in transmission, so there's no need to worry.
