As a father of three daughters, this article scared the pants off of me! LOL!

After midnight on a rainy night last week in Chapel Hill, N.C., a large group of sorority women at the University of North Carolina squeezed into the corner booth of a gritty basement bar. Bathed in a neon glow, they splashed beer from pitchers, traded jokes and belted out lyrics to a Taylor Swift heartache anthem thundering overhead. As a night out, it had everything — except guys.

"This is so typical, like all nights, 10 out of 10," said Kate Andrew, a senior from Albemarle, N.C. The experience has grown tiresome: they slip on tight-fitting tops, hair sculpted, makeup just so, all for the benefit of one another, Ms. Andrew said, "because there are no guys."

North Carolina, with a student body that is nearly 60 percent female, is just one of many large universities that at times feel eerily like women's colleges. Women have represented about 57 percent of enrollments at American colleges since at least 2000, according to a recent report by the American Council on Education. Researchers there cite several reasons: women tend to have higher grades; men tend to drop out in disproportionate numbers; and female enrollment skews higher among older students, low-income students, and black and Hispanic students.

In terms of academic advancement, this is hardly the worst news for women — hoist a mug for female achievement. And certainly, women are primarily in college not because they are looking for men, but because they want to earn a degree.

But surrounded by so many other successful women, they often find it harder than expected to find a date on a Friday night.

…Students interviewed here said they believed their mating rituals reflected those of college students anywhere. But many of them — men and women alike — said that the lopsided population tends to skew behavior.

"A lot of my friends will meet someone and go home for the night and just hope for the best the next morning," Ms. Lynch said. "They'll text them and say: 'I had a great time. Want to hang out next week?' And they don't respond."

Even worse, "Girls feel pressured to do more than they're comfortable with, to lock it down," Ms. Lynch said.

As for a man's cheating, "that's a thing that girls let slide, because you have to," said Emily Kennard, a junior at North Carolina. "If you don't let it slide, you don't have a boyfriend."
