Can we blame this on Hustle N Flow, Young Buck or Three Six Mafia? I bet they’ll find a way…

If you need a little push to talk to your kids about sex, birth control and abstinence, consider this scary story: One Memphis high school has 90 pregnant students. That’s 20 percent of the school’s female population.

“It ain’t nothing new,” 16-year-old Tarika Sutton, who has a 2-month-old, told TODAY. “Some girls try to do it ’cause they think it’s cute.”

It doesn’t look like there is any “pregnancy pact” going on — just a bunch of unprotected sex, and kids having babies. The good news is that the teen birth rate has been steadily declining and in 2009 hit its lowest level since the government started tracking teen pregnancies in the 1940s. But the U.S. teen birth rate is still higher than other First World countries.

Psychiatrist Janet Taylor tells TODAY’s Meredith Vieira that parents should start talking about sex and saying “no” early — at 8, 9, 10. (Taylor has four daughters, ages 17 to 23, so she’s speaking from experience.) Psychologist Dale Atkins says sex education should actually start even earlier, even before you get into the actual birds-and-bees talk: “It’s all about awareness of your body, and it’s your body, and how you handle it, and how you treat it, and what you can say yes and no to.”

So, when do you start talking to your kids about sex, pregnancy, birth control and abstinence — 8? 12? 6? And what do you say?
