If punters don't want to catch anything from having unprotected sex, it's best not to have unprotected sex. We don't have the Sex Police, and nobody is going to tell me (or anybody else here, since I doubt any of us would appreciate it) what I can and can't do with my body - I'm nearly 50 and I'll shag whoever I like, however I like. I don't offer OWO or RO, but I'm not whinging about those who do.
It's.worth pointing out that a lot of people would think we were all pretty desperate for doing sex work in the first place, so pointing the finger and looking down our noses at each other is even less helpful. On the health side, I just assume they're all riddled.
