As we have fewer and fewer antibiotic this sort this type of behavior will become self eliminating.

Unfortunately, your Obamacare dollar will be preferentially spent on those infected through their unnatural acts with multiple partners, but granny won't get that shiny new stent because the funds won't be there...
I think the primary hidden reason for Obamacare, was to provide coverage for HIV+ men. With treatment, HIV can be suppressed for many years -- at a lifetime cost of $379,000 (in 2010 dollars). Without expensive treatment, the gay community will see the die-off they were experiencing in the early 1990's.
But, eventually, a strain of HIV will mutate and be resistant to all current treatments. This strain will then spread all through the gay community as fast as the original strain of HIV spread.
