HIV is a fragile virus that looses its activity out of the body. There has never been a single transmission this way, basically because there cannot be.
The only transmission ways are :
-Unprotected anal/vaginal penetrations.
-Sharing needles to inject drugs.
-Mother to child.
In some media you still find a lot of "theoretical" risk that have never resulted in a transmission. So, please, read what I have just written.
There is nothing you can add to your activities or sexual encounters apart from what I have just let you know that could be a risk.
All the best,
DragonPulse.
It wouldn't be a risk at any time under any conditions. Only sex risks are unprotected penetrating vaginal or anal and only non-sex risk is sharing needles that you inject with.
