Blood on toilet paper/hemorroids

Hi, ive posted before but this is a new issue. I suffer from hemorroids and i frequently notice blood on toilet paper when i use it. My concern is that once without realising i smeared some blood onto the toilet roll and dispenser and also the tiles behind the toilet roll(a small amount) and i am worried that someone would then immediately use the blood stained loo roll and wipe their back passage with it and even possibly their own bloody hemorroids and then it would be a blood to blood transfer. Im currently awating a test but assuming im hiv+ should i be worried in this instance? cheers

Hello,
You would need to be HIV positive in the first place. You need to wait for your result first before you worry unnecessarily.
In any case, it is highly unlikely that someone would get infected that way, as the virus becomes unstable very quickly outside of the body and within minutes is not viable.
Best wishes,
José

My risk is fairly low, i gave oral sex to someone on two separate occasions and had semen in my mouth. I have read that hiv cannot be caught from environmental surfaces, would that be the case in the above situation, would my blood on the tissue and tiles be not viable as soon as it was on the environmental surface?

Yes, that would the case.

José
