It might be excessive, but I see sexuality in America as horribly repressed.  An R rated film screened in the US is so rated because of sexuality, while the same rating would be determined based on violence in European countries.  Americans see sex as something taboo, but are hypocritical by putting excessively sexual connotations into many television ads and shows.  Even children's programs have sexual undercurrents.  But most of this is completely heterosexual.  If a man is to display any sort of affection for another, people assume immediately that he is gay.  The cultural difference between America's perceived healthy heterosexual-centric sexuality to the rest of the world is how I see the situation.
