Wha? America is sexually repressed/repressive? Do you watch TV or movies?
You can literally go anywhere in this country and hook up with anyone for sex at any time. So long as nothing is forced, and you aren't directly paying for it (a law which I agree is odd), sex is totally unrepressed here. All with no general cultural repercussions.
I don't know how anyone can claim America, in general, is a sexually repressive culture.

I disagree. You can show gratuitous violence on a PG-13, but let one nipple slip and it's automatically rated R. People that worked in the adult industry (legally or illegally) have trouble with employment once they leave unless they successfully bury that aspect of their past.
And have you seen some of the laws on the books? Many laws against things like sodomy were only overturned by court rulings, not by legislative votes. As individuals a great many people have slept around, but as a society we look down on such things. Consensual sex between minors is still against the law in many states. Statutory rape is sometimes taken to the extreme where an 18 year-old guy is charged for having sex with his girlfriend that was days away from being 18.
And what are popular sayings in rape cases? "Did you see the way she dressed, she definitely had it coming".
Prostitution is illegal (unless you are paying to video tape it, then it's porn and that's somehow ok). Strip clubs vary from full nudity to must be in at least a bikini depending on how prudish the state is. And I don't know of any where the customer is allowed to touch the dancer.
Parents and religious groups still fight teaching sex ed in schools despite numerous studies showing the benefits of doing so. Teens that become pregnant are often shamed out of school rather than being supported so that they can actually have a future. Children are taught to be ashamed of themselves, to the point where most people will use words like "privates" "hoo-hoo" or whatever rather than use the actual names of those dirty dirty parts of your body.
There are places in the country where adult stores are driven out of business and can only exist as a sort of underground deal where you have to know where to go and speak the magic code word.
Big cities tend to be a bit better, but as you get into suburban and rural areas, there is most definitely a prudish anti-sex attitude in many areas of the country.
We aren't as repressive as Saudi Arabia, but I'd hardly call America sexually enlightened.
