This is not science. If you gave this same survey to a bunch of people from "The Greatest Generation", especially ones that have been married 40, 50, or more years you would get much different answers and values attached to sex. If this study proves anything, it's the erosion of values in our society. Please stop passing this crap off as science and legitimate research, and view it for what it is. For the record, I'm a young 30-something that sees sex much differently than most of my generation. It's shameful that you continue to undermine good values. Instead of looking at the reasons why people have sex, try looking at the reasons why they don't value it and cheapen it and temselves.
