Plate came over with 2 wicked herpes sores on her face. She jumped in my bed and tried to start shit but I pulled back and said "is that contagious?"

I know over half of people have the virus and I probably have it too.

But my question is what should I have done? I'm not cool with hooking up with a girl while the sores are open they're nasty af imo. As soon as I asked her if it was contagious she left and hard nexted me lol. I have other plates and I don't want her back. I just want some advice of how I should have framed that situation?
