Sex isn't a taboo anymore at all.  Neither are drugs, porn, or any other form of illicit entertainment.  Drinking, tripping high on crack, and banging 4 hookers?  Totally cool.<br/><br/>Nonetheless, if you're really depraved there's still a censure, and people in authority are expected to cut most of that shit out (sex is okay so long as it isn't too crazy).<br/><br/>All in making more babies, given the human race basically in a war for survival and all. There's some hints that the birth control pills and other contraceptives they sell are purposefully tampered with to be less effective, except for key personnel.
