mmdv26, I have an older friend who wasn't a 60s child but came of age in the 70s before AIDS and never used a rubber with any of his girlfriends.
Of course anything you could catch back then (except herpes, of course) could be cured with a shot of antibiotics which a high-school friend of his needed after catching the clap from his promiscuous girlfriend (balls swelled up to grapefruits).
But pretty much everyone I know now uses a rubber pretty regular even though the chance of catching AIDS for a non-gay, non drug-using guy is pretty damn low.
Still, like others have been posting, if a strange girl lets you bareback her chances are she's letting others do the same and you have no idea about her other partners.
Damn, it seems like sex used to be so much simpler before AIDS, and now we've got to worry about HPV too (though we've got a vaccine for that).
I should find an AIDS cure or vaccine just for my own damn sex life.
