[The reason is Jeff. Or Harley. Depends on perspective. Will hopes Rincewind doesn't turn much redder, doesn't make some long, loud noise. It may attract attention from others and that's surely just bound to make things even more awkward.

I did. [Maybe it's good Rincewind focuses on that. Maybe he'll do his own research later and decide better that way.] If someone's infected, it's possible to spread that through contact with bodily fluids. Blood, vaginal fluids, semen. It can spread through sores, too, and other methods that aren't sexual. [He doesn't think they have to worry about Rincewind using needles. God, he hopes.] So there are methods to protect yourself. Comes in handy if you don't know your partner's medical history very well.
