"College kids are more educated, more affluent, and may not be indicative of all kids that age," says Dr. Martin Drell, Professor and Head of Child and Adolescent Psychiatry at LSU Health Sciences Center.
But hooking up, or casual sex outside a serious relationship is much more prevalent this study finds.
"Hooking up is a reality. I see a lot of college kids in my practice and there is a certain more informality to sexuality now, for some of the kids," Dr. Drell says.
While 25 years ago some kids may have been stressed about their virginity, some of these kids now have anxiety about he says is whether they're are ever going to find intimacy. "And whether the person is ever going to have a relationship with them, like them and respect them."
