Haha, yeah, my grammar's failing this weekend, I'm a little shattered.
As for cultural differences, I'm referring to the common things I see on the message boards I frequent, which is largely here right now but a handful of other places over the years, and the occasional news media story or something trending on Twitter.
Yes, I understand your national diversity, we have that, too, remarkably so for a small nation. But it does seem from my perspective that there is a lot more likelihood that you'll find someone in the States with fewer than ten, or even five, intercourse partners in their life than you will here.
There also seems that there's a lot more use of the word "slut" over there, too, even in reclamation of the term. I get the impression that there's still abstinence based sex ed in your schools, too, which we don't have, and didn't even when I was at school. Even when I was going to Christian camps as a young teen, the message was "keep that special thing for your special person you'll marry" rather than any negative message about sluts and brimstone. And the message we got definitely wasn't targeted just at girls.
Of course, our current teenagers are experiencing quite a different culture to what I did - and a lot of it more negative - but for my generation/my friends and peers, we just didn't have a lot of hang ups about the variety of sex and sexual partners that still seems frowned upon broadly in the States from an outsiders perspective.
