Unprotected sexual freedom is completely a practical goal; condoms work well but many choose not to use them, for better or worse. Prevention doesn't even need to center around eradication of the disease; it could come in the form of home detection kits. For better or worse people will always have unprotected sex with strangers. It's a thing.

I'm a little tired of the disconnect between medical advice and reality when it comes to sexual practices. Dental dams, anyone? Sure they're smart; I don't think I've seen one outside of health class. Doctors could easily provide more helpful advice.
