Oh, I know. When I see one whipped out (with a baby attached to it, lol) I get uncomfortable and look away as well.
I'm just saying, it's our fault we see it like that. Not directly US, but our society as a whole and the people who shaped it.
Like you said before, America is really conservative & private. The first two things that come to mind is gays and nude/topless beaches. In many many other countries those things are 100% perfectly normal.
The US is (sort of) ahead in many things like technology and science, but we're way behind in things like social equality.
Oh, and fashion. I see my cousins in Spain wearing these really cool things and I'm like "Dang! We won't get those for another year or two!".
