Not only abstinence fails to prevent AIDS, its peddlers are lying bastards.
Summary? Perhaps the greatest proponent of abstinence as means to combat sexually transmitted diseases in the United States of America has been caught red-handed. Yup, he's a consumer of prostitute services. Again: he fucks with whores.
Do you see the irony?
I don't know what's worse: these "nannies" fucking whores, or them giving dramatically stupid advice regarding what to do with our lives.
The botom line: abstinence doesn't work, it never has, it's against human nature, and whoever says abstinence works is a stupid moron who probably doesn't practice it either.
