I currently have a fever blister that has been healing for a couple of days now and I've been putting Zovirax on it at night before bed. I completely forgot what was going on with my lip and liked and succeed a guys scrotum. I did not suck his penis, just the scrotum and testicles. Can I contract HIV from what I did since I have a healing fever blister? There were no fluids of any kind involved...just me licking his scrotum and suckling on his testicles. Will I be okay? Do I need to worry about HIV?
