Trust isn’t the issue. Probability is. Even without deception, there’s a chance someone can have an STD without knowing it. And there’s a chance that std won’t show up on testing due to incubation times, dormancy phases, and false negatives.
Imagine there is a 1% chance of your partner having an STD without knowing it. 1% doesn’t sound too bad an odds. But if you have 50 partners in an extended polycule, then the chance that at least one of them unknowingly has one is 1-(.99)^50, or 39%. Probabilities compound.
