Fewer teens are having sex

or more teens are having less sex.

I don't understand why this is so for boys, having never been one. But for girls, perhaps the sight of high school youths sloping home from school decked out in baggy jeans and hoodies, with the hood concealing most of their faces, looking for all the world like burglars, is not an inspiring one. Perhaps, given what's on offer, the young ladies would rather do their homework or go shopping.
