I had protected sex with a prostitute. but i had an small itchy wart on my left testicle so the skin above it was irritated but not bleeding and i'm scared that some of her vaginal fluid may have touched it. is this a way to get hiv? thanks?

It would take transmission from vaginal secretions to enter your blood stream through that wart and I think that's quite unlikely. Nevertheless, in my experience with this type of scenario,you may not have peace of mind unless you have appropriate HIV testing. Your public health office can advise you about the various tests available but don't test too soon as a false negative result can occur

In this scenario no.. You can get tested to make sure
