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.

Maybe in the age of nanobots will we have practical ways to allow for unprotected random sex.
