Not sure what exactly you're referring to. It's virtually impossible to prosecute most sexual crimes. And if somebody's really out to frame you, the truth doesn't matter in the first place. Getting murdered by an angry lover may be more likely.

All this does is make people think twice. If you're married and trying to have children how can any craziness ever happen? Not sure what "collective sex-culture" is, but it may be what many just call "promiscuity" (which is kind of my point).
