What if you caught an STD from your partner? It’s not AIDS or anything, but a nagging burning disease which does require it be treated with a few visits to the clinic. You confront them about it, but they swear to you they’ve been faithful and they must have caught it in the locker room at the gym. They’ve never cheated on you, and you do trust them, but it’s a STD, of which the first two letters stand for “sexually transmitted” so now you’re worried. Also, you have a STD to deal with. There’s got to be some sort of penalty for that, even if it was accidental, right?
