Sexual Weirdtopia could just be "the internet comes to life"... e.g. everyone gets freaky without shame, but it turns out almost everyone is into something that's of absolutely no interest to you personally.

Or, to follow the public science example, the taboo is revealed to be as fundamental aspect of sexual arousal as the unknown is to the intellectual. The people demand a strict morality police after an era of total acceptance drains all the fun out of it. Everyone is fully expected to both seek out sexual thrills and aid in the swift punishment of anyone who seeks out sexual thrills: If you ask for a spanking you may be asking for a spanking.
