Men used to carry a condom in their wallet, now they carry a print out of their last STD results, signed and notarized.
Mmm let me go back in time when I met Mrs. Ustwo, and mind you this was in the height of the AIDS scare.........
Lets see shes 18, naked, and wants me, and I say 'Baby, not until you get tested, its about trust.'.
Mmmm nope can't see that one happening.
