Trollbabe said: the love-in "if it feels good, do it" seventies. (How we ended up with the AIDS epidemic.)
The HIV/AIDS epidemic in the U.S. had little to do with feel-good attitudes toward sex, and much more to do with the indifference of public health authorities
to its appearance. It spreads through ignorance, not love-ins, which is why sexually-liberal western Europe has relatively few cases, whereas sexually-conservative Africa has it worse than anywhere.
I wouldn't wear a flared leather condom with tassles, though. There has to be a limit somewhere!
