Well, admittedly, we're talking about a country where oral sex wasn't seen as actual sex by the president himself. There is something in the "American" generalization.

And how about that little episode where there was a wide movement for abstaining from sex until marriage in young adults - mostly as a way to safeguard against STD - and then the average number of cases of STD didn't move an inch... because the "young adults" didn't see oral sex and anal sex as breaking chastity.
