Even though the first sentence doesn't really go with the rest of the article, and isn't backed up anywhere (strange), here's another study that says that abstinence-only sex education doesn't delay sexual activity. It's a rather short article by the Richmond Times-Dispatch which I wish would have been longer and more detailed, but here you go.
On a separate note, Brickweekly.com is actually a lot more fun to read than the actual newspaper (and I rarely say that because I love actually holding a newspaper. I think all papers should be the size/specs of Style Weekly and Brick because they are much easier to hold and read. ) As a foodie, I also love all of Brick's food/drink articles.
