The good news is that women's roles have changed so dramatically over the past three decades that women now expect to have careers, balance work and family, express their individual autonomy.

Guys constantly talk about pornography in two ways: as revenge and as reassurance. When you live in a world in which beautiful, sexy women are all around you, in the same classes, on the same athletic field, competing for the same jobs, then the pornographic world - the world in which women thrill to male sexual desire - reassures men that although they may feel "one down," they're still entitled to women's bodies.

Playing along with Guyland may be the only way an individual woman might believe she has a chance at a social life or a relationship. Sometimes it gets pretty crazy, like a sorority requiring that all the pledges sleep with the members of the "brother" fraternity.

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.

It's like what you might call Goldilocks' dilemma in the old fairy tale. Young men see women as "less than" or "better than," but never their equals. And studies indicate that equality is the best foundation for a healthy relationship.

I believe that Americans are entitled. We're entitled to have a job that makes us feel like we have some dignity in our lives, that we live a life of integrity, and that we have good family relationships and our relationships with our friends and our families and our coworkers are enriching and meaningful.

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