No surprise there.  We were a nation founded by Puritans who have had us in their nasty grip ever since.  I think there was a brief respite in the 60s and 70s but there has been a major conservative backlash since then.  Sex is simply not addressed in any healthy way in the public sphere.

The difference between conservative parties with Christian roots in Europe and with secular roots in the USA:

Actually, it the US conservative party is anything but secular.  

The perceived and real level of sophistication in the public spheres of the USA and Europe:

Well, please don't lump all of America in with Tennessee.  We're talking a pretty rural state.  And if you are looking for a level of sophistication, do not expect to find it in our campaign ads.  These are designed specifically to get racist idiots to the polls.

How is sex framed in the Austrian ad? Is it possible to run a similar advertisement anywhere in the United States?:

I think you could do it in NYC, San Fransisco, LA, Miami, maybe Chicago...  The big problem is with advertisers who might threaten to pull their business if someone airs something too "liberal."

How is sex framed in the American ad? Is it possible to run a similar advertisement anywhere in the European Union?

God, I hope not.  For the record, the ad has been pulled after charged as racist, so you could argue it is not even possible to run it here.  I don't think this ad says as much about America as it does about the Republican Party.  They are just that disgusting.

Also worth noting: the Austrian ad appears to target the youth?  (I might be wrong.)  The GOP ad is targetting older people.  They vote the most and are most conservative.  And are from a different era.  FWIW, pre-marital sex of the type in the Austrain add is just a common here as it is anywhere.
