My colleagues and I have done a survey of 13,000 students on more than 17 campuses, and we found that while sex in college has always been a bit more casual, "hooking up" has pretty much replaced other traditional forms of dating.

Feminism loves men enough to expect them to act more honorably and actually believes them capable of doing so.

My colleagues and I have done a survey of 13,000 students on more than 17 campuses, and we found that while sex in college has always been a bit more casual, "hooking up" has pretty much replaced other traditional forms of dating.

And few hookups, if any, ever take place sober. And while wearing "beer goggles" may make people appear more attractive, it doesn't exactly make for sexual ecstasy! There's always been a difference between pleasure and scoring.

We have the data to prove to men that gender equality is not a zero-sum game, but a win-win.

Many guys see relationships with women as a zero-sum game: If she wins, he loses. Marriage is the ultimate contest: Her job is to get him to capitulate to marriage. So many men see marriage as the "end of freedom," the end of boyhood. That's why bachelor parties are supposed to revel in that boyish irresponsibility "one last time." So many guys figure, "Why rush into something that means basically that you'll be a prisoner forever?"

Ironically, survey after survey shows that married men are happier and healthier than unmarried men. Oh, and they also have more sex.
