Are attitudes about sex the difference between the Democrats and Republicans? Opposition to traditional morality seems to be popular with a lot of libertarians as well.

This reminds me of the most stupid argument brought to bear against the bill of impeachment against Bill Clinton, that the issue was "just about sex," as though sex, infidelity, etc. were totally unimportant to society. If that were true, we wouldn't have the huge porn industry we have, or huge numbers of babies born out of wedlock, R and X rated movies, marriages destroyed by infidelity and murders motivated by jealousy. I think that the sexual revolution will continue to make inroads into popular media, but I don't see that as a good thing, because attitudes toward it are uniformly wrong. Sex is important in our lives and a powerful force that build or weaken society, depending on whether we respect it and impose limits on ourselves or just treat it as recreation, with no more importance to our lives than bodily functions.
