Edit: Oh geez. I guess I might’ve just gotten worked up on just the stigma. Hell, I wonder if I gave it to her now. I’ve slept around way more than her.
Edit 2: I cut out the whole long story because I’m a bit embarrassed to have overthought it so much and I guess it’s not really relevant. I’ll leave the post up so maybe other anxious people can see the responses.
The spark notes version is: I loved a girl and let her go and when she came back, she and I worried about her having herpes.
Your point stands, but the math doesn’t work like that. Some people would have both, so in total the amount of people with any type of herpes would be 67%+0.33*13% = 71%.
And around 9% of people have both types, but they’re already included in that 71%.
