HIV is inactivated in =air which means it can't infect from air contact and what you did is classified as air contact. Zero risk.
No one in 40 years of history got HIV from air contact. Even with blood, lactation cuts, rashes, burns etc air does not allow inactivated virus to infect, so you had zero risk.
There is a std forum for that info.
Hello, as stated, hand jobs are not a means of HIV transmission. While you may visit our STD forum, that is also an unlikely scenario for STD transmission for STD's as well. You do not describe something that poses a risk for either. We wish you the best.
