HIV can take years to show, so all you can do is take the odds that if it were to happen, it'd happen sooner than later, and go based on your first "HIV rapid" test results. Second, HPV the body can clear on its own and most everyone has some form of it or another, just that some cause bumps similar to HSV. HSV you can never get rid of, so id be more concerned with that and a multitude of other STD's. If this was just your average girl that you cheated on with then I would say to keep it under wraps AKA wrapped, until you get tested and cleared. There's always excuses you could give as to why you started wrapping it up if you hadn't before such as pregnancy risk. Just that you wouldn't be able to hide it if she decides that she wants to go down on you. However, considering this scenario I would say you should really inform your girlfriend no matter how cringe worthy it is. It's only right.
