One morning a couple of years ago, Tyler Barnett woke up with a woman he barely knew. No surprise there: He was just your garden-variety twentysomething guy, a P.R. man in Los Angeles who enjoyed casual, commitment-free hook-ups. Yet sometime before dawn, something in him shifted. And once the sun was up, he decided he was over casual sex. He chased her out with a flimsy excuse: that he had to get to work.

Sure, Barnett was concerned about STDs and pregnancy. But mostly he'd gotten fed up with putting out. And he's not alone. These days, in seeming defiance of male sexual stereotypes, the guy is suddenly the one saying no.
