You had another thread where risks were described to you. The risks for HIV are very clear. They include 1. having penetrating unprotected vaginal intercourse, 2. having penetrating unprotected anal intercourse or 3. sharing injectable IV drug needles. Those are the only risks. You previously asked about oral sex. That is not a risk because air and saliva are involved. Anything that you describe here also has air involved, does it not? You can't get HIV from a foot touching a wart. There is NO credible source that says that has ever happened. There is not a proven case ANYWHERE. So, this is another NON risk you are asking about and ANYTHING that is not one of the above three mentioned activities is a non risk. Please apply that to your future questions as you should be able to then know the answer on your own and not have anxiety over your activity.
Hi,
You describe an unlikely event to begin with. So the chance would be zero.
No need to worry about stepping on ejaculated cum or blood, as we wear shoes.
