Hey, let's be honest: Sometimes, things happen. Someone else's underwear ends up in your possession, and before you know it, you're wearing another person's unmentionables. It's only later that you find stains on the underwear: They might excite you or they might disgust you, but in the end, they set off all kinds of anxieties about your health.
You can rest assured. Whatever body fluid might be dried on a piece of clothing, HIV doesn't survive long enough outside the body for it to pose a risk. There's no way you could pick up HIV this way.
