"In all things erotic", writes Adam Gopnik, "morals and manners run at right angles to each other".

Adam argues that the much discussed "sex recession" in the US is primarily a question of misunderstanding between generations - and is certainly not a cause for moral panic!

"We misread the sex because the signs change, and we misread the signs to mean that the sex is changing...or even that the sex is vanishing".
