Nationally, women now outnumber men in college enrollment by 4 to 3, leading some researchers to argue that the gender imbalance fosters a culture of hooking up because men, as the minority and limiting factor, hold more power in the sexual marketplace and use it to pursue their preference of casual sex over long-term relationships.
