We Like Our Friends - A Lot

Many think of having "friends with benefits" as something that kids do in college, but Indiana University researcher Dr. Debby Herbenick tells CBS News that she was surprised to find that such a large number of people over 30 had their last sexual experience with a buddy.

Overall, the study found that 13 percent of men and 11 percent of women aged 19-59 said their last sexual encounter was with a friend.
