For the many who are delaying the responsibilities of marriage and child-rearing, hooking up has virtually replaced dating.
It is a major shift in the culture over the past few decades, says Kathleen Bogle, a professor of sociology and criminal justice at La Salle University.
Young people during one of the most sexually active periods of their lives aren't necessarily looking for a mate. What used to be a mate-seeking ritual has shifted to hookups: sexual encounters with no strings attached.
"The idea used to be you are going to date someone that is going to lead to something sexual happening," Bogle says. "In the hookup era, something sexual happens, even though it may be less than sexual intercourse, that may or may not ever lead to dating.".......more from NPR
