In the U.S. there’s a belief that, when it comes to sex, girls and boys are engaged in a battle instead of a relationship and there’s resistance to the idea that boys and girls can both feel both love and lust… The U.S. is very strongly tied to the model of marriage. We don’t want 15- or 16- or 17-year-olds to marry but we don’t think a relationship is love unless it’s the one and only, the person you’re going to marry forever.
